Ævar Arnfjörð Bjarmason 2a59a6ef20 tests: fix and add lint for non-portable head -c N
The "head -c BYTES" option is non-portable (not in POSIX[1]). Change
such invocations to use the test_copy_bytes wrapper added in
48860819e8 ("t9300: factor out portable "head -c" replacement",
2016-06-30).

This fixes a test added in 9d2e330b17 ("ewah_read_mmap: bounds-check
mmap reads", 2018-06-14), which has been breaking
t5310-pack-bitmaps.sh on OpenBSD since 2.18.0. The OpenBSD ports
already have a similar workaround after their upgrade to 2.18.0[2].

I have not tested this on IRIX, but according to 4de0bbd898 ("t9300:
use perl "head -c" clone in place of "dd bs=1 count=16000" kluge",
2010-12-13) this invocation would have broken things there too.

Also, change a valgrind-specific codepath in test-lib.sh to use this
wrapper. Given where valgrind runs I don't think this would ever
become a portability issue in practice, but it's easier to just use
the wrapper than introduce some exception for the "make test-lint"
check being added here.

# SANITY is about "can you correctly predict what the filesystem would
# do by only looking at the permission bits of the files and

# suite as root, where a test may expect "chmod -r file && cat file"
# to fail because file is supposed to be unreadable after a successful
# chmod. In an environment (i.e. combination of what filesystem is
# being used and who is running the tests) that lacks SANITY, you may
# be able to delete or create a file when the containing directory
# doesn't have write permissions, or access a file even if the
# containing directory doesn't have read or execute permissions.
