Since the library is dlopen()ed by libpthread and required during
pthread_exit()/pthread_cancel(), let's install it explicitly if available to
avoid unexpected fails in tests. This also consolidates all related
workarounds for this library across the test scripts.
TEST-70 specified its own EXIT handler, which replaced the
`cleanup_loopdev` handler, so the loop device was always hanging around
once this test was run. Let's use the new `add_at_exit_handler()` stuff
to mitigate this.
On Ubuntu, cryptsetup does not link against libgcc_s.so.1 which leads to
the following test failure in TEST-70-TPM2:
systemd[1]: Starting testsuite-70.service...

To fix this, manually install libgcc_s.so.1 to the test image if running
on Debian-like systems.
Add tests for enrolling and unlocking. Various cases are tested:
- Default PCR 7 policy w/o PIN, good and bad cases (wrong PCR)
- PCR 7 + PIN policy, good and bad cases (wrong PCR, wrong PIN)
- Non-default PCR 0+7 policy w/o PIN, good and bad cases (wrong PCR 0)
v2: rename test, fix tss2 library installation, fix CI failures
v3: fix ppc64, load module
