thread_pthread: stop trying to deal with cancellation
We don't use pthreads cancellation ourselves and it's painful to
use correctly. Any cancelled threads would break
vm->living_threads, GVL, thread_sync.c, autoload, etc...
So don't bother caring; because we can't stop rogue extensions
from completely breaking the VM in other ways, either.
