  [rtsan][compiler-rt] Prevent UB hang in rtsan lock unit tests (#104733)

It is undefined behavior to lock or unlock an uninitialized lock, and
unlock a lock which isn't locked.

Introduce a fixture to set up and tear down the locks where
appropriate, and separates them into two tests (realtime death and non
realtime survival) so each test is guaranteed a fresh lock.
