KVM: selftests: Add helper APIs to cancel+join pthreads

Browse source

Deduplicate test code that does cancel()+join() on pthreads by adding a
collection of syscall wrappers.  The tests that asynchronously cancel
pthreads, i.e. use PTHREAD_CANCEL_ASYNCHRONOUS, are particularly ugly,
especially since it's not immediately obvious why those tests assert on
the thread being CANCELED, whereas others do not.

No functional change intended.
