thread_sync.c (rb_mutex_lock): acquire lock before being killed
We (the thread acquiring the mutex) need to acquire the mutex
before being killed to work with ConditionVariable#wait.
Thus we reinstate the acquire-immediately-after-sleeping logic
from pre-r63711 while still retaining the
acquire-after-checking-for-interrupts logic from r63711.
This regression was introduced in
commit 501069b8a4013f2e3fdde35c50e9527ef0061963 (r63711)
