Updating suppression for 101853

tools/valgrind/tsan/suppressions_mac.txt

 # There are two kinds of suppressions in this file.
 # 1. third party stuff we have no control over
 #
 # 2. Intentional unit test errors, or stuff that is somehow a false positive
 # in our own code, or stuff that is so trivial it's not worth fixing
 #
 # 3. Suppressions for real chromium bugs that are not yet fixed.
 # These should all be in chromium's bug tracking system (but a few aren't yet).
 # Periodically we should sweep this file and the bug tracker clean by
 # running overnight and removing outdated bugs/suppressions.
