[test][llvm-cxxfilt] Fix darwin build bot 

When committing dba420bc05, I missed that a darwin-specific change had
been recently introduced into llvm-cxxfilt, which my change ignored and
consequently broke the darwin build bot. This change fixes this issue as
well as improving naming/commenting of things related to this point so
that people are less likely to run into the same issue as I did.
