Chang symbol name check to require an exact match with the TSan
initializer called from the module ctor. This should avoid
accidental matches, e.g., `__tsan_testonly_barrier_wait` in tests.
My assumption is that this symbol is present in all modules
instrumented with TSan.

Add non-platform specific test. (I kept the existing test for
Darwin because it tests a specific system API.)
