thread_sync.c (rb_mutex_sleep): disable interrupt checking in ensure
This is needed to reliably fix ConditionVariable#wait on Thread#kill
[Bug #14999] because there is still a chance an interrupt could fire
and prevent lock acquisition after an ensure statement.
Arguably, rb_mutex_lock itself should be uninterruptible, but that
already prevents bootstraptest/test_thread.rb from completing and
probably breaks existing use cases.
For reference, POSIX expressly forbids EINTR from pthread_mutex_lock.
