Pekka Paalanen 3179e0f0e0 CI: work around LeakSanitizer crashes with use_tls=0 
Without this fix, we have randomly been getting CI failures due to
LeakSanitizer itself crashing after all the tests in a program have
succeeded. This has been happening randomly for a long time, but
https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/1486
made it very reliably repeatable in the job x86_64-debian-full-build
(and no other job) in the test-subsurface-shot program.

--- Fixture 2 (GL) ok: passed 4, skipped 0, failed 0, total 4
Tracer caught signal 11: addr=0x1b8 pc=0x7f6b3ba640f0 sp=0x7f6b2cc77d10
==489==LeakSanitizer has encountered a fatal error.

I was also able to get a core file after twiddling, but there it ended
up with lsan aborting itself rather than a segfault.

We got some clues that use_tls=0 might work around this, from
https://github.com/google/sanitizers/issues/1342
https://github.com/google/sanitizers/issues/1409
and some other projects that have cargo-culted the same workaround.

Using that cause more false leaks to appear, so they need to be
suppressed. I suppose we are not interested in catching leaks in glib
using code, so I opted to suppress g_malloc0 altogether. Pinpointing it
better might have required much more slower stack tracing.

wl_shm_buffer_begin_access() uses TLS, so no wonder it gets flagged.

ld-*.so is simply uninteresting to us, and it got flagged too.

Since this might have been fixed already in LeakSanitizer upstream, who
knows, leave some notes to revisit this when we upgrade that in CI.

This fix seems to make the branch of
https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/1486
in my quick testing.

# This file uses the freedesktop ci-templates to build Weston and run our
# tests in CI.
#
# ci-templates uses a multi-stage build process. First, the base container
# image is built which contains the core distribution, the toolchain, and
# all our build dependencies. This container is aggressively cached; if a
# container image matching $FDO_DISTRIBUTION_TAG is found in either the
# upstream repo (wayland/weston) or the user's downstream repo, it is
# reused for the build. This gives us predictability of build and far
# quicker runtimes, however it means that any changes to the base container
# must also change $FDO_DISTRIBUTION_TAG. When changing this, please use
# the current date as well as a unique build identifier.
#
# After the container is either rebuilt (tag mismatch) or reused (tag
# previously used), the build stage executes within this container.
#
# The final stage is used to expose documentation and coverage information,
# including publishing documentation to the public site when built on the
# main branch.
#
# Apart from the 'variables', 'include', and 'stages' top-level anchors,
# everything not beginning with a dot ('.') is the name of a job which will
# be executed as part of CI, unless the rules specify that it should not be
# run.
#
# Variables prefixed with CI_ are generally provided by GitLab itself;
# variables prefixed with FDO_ and templates prefixed by .fdo are provided
# by the ci-templates.
#
# For more information on GitLab CI, including the YAML syntax, see:
# https://docs.gitlab.com/ee/ci/yaml/README.html
#
# Note that freedesktop.org uses the 'Community Edition' of GitLab, so features
# marked as 'premium' or 'ultimate' are not available to us.
