Log:
Handle NetBSD alias for pthread_sigmask

Summary:
Add a new helper macro TSAN_INTERCEPTOR_NETBSD_ALIAS_THR2
that handles pthread(3)/libc aliases in scenarios when a name in both
libraries differs not just in prefix namespace.

Handle TSan pthread_sigmask mangling accordingly into __libc_thr_sigsetmask.
