sanitizer-common: fix buildbot by temporarily disabling release_to_os test for tsan

This has been causing substantial redness in the buildbots e.g.,
https://lab.llvm.org/buildbot/#/builders/239/builds/2405
which already contained a commit to deflake the test
(https://github.com/llvm/llvm-project/commit/3afd1b2c357fb5353084a736d885af60115d6acb).
Temporarily disabling the test to prevent this error from
hiding other potential problems.
