Subject: process.c: simplify SIGCHLD-based waitpid

Introduce a new rb_thread_sleep_interruptible that does not
execute interrupts before sleeping.  Skipping the interrupt
check before sleep is required for out-of-GVL ruby_waitpid_all
to function properly when setting waitpid_state.ret

Now that ubf_select can be called by the gvl.timer thread
without recursive locking gvl.lock, we can safely use
rb_threadptr_interrupt to deal with waking up sleeping
processes,
