Ignore the result of pthread_kill in ubf_wakeup_thread
After an upgrade to Ruby 3.3.0, I experienced reproducible production crashes of the form: [BUG] pthread_kill: No such process (ESRCH) This is the only pthread_kill call in Ruby. The result of pthread_kill was previously ignored in Ruby 3.2 and below. Checking the result was added in be1bbd5b7d40ad863ab35097765d3754726bbd54 (MaNy). I have not yet been able to create a minimal self-contained example, but it should be safe to remove the checks.
