tests/thread: Allow thread tests to pass with the native emitter.
The native emitter will not release/bounce the GIL when running code, so
if it runs tight loops then no other threads get a chance to run (if the
GIL is enabled). So for the thread tests, explicitly include a call to
`time.sleep(0)` (or equivalent) to bounce the GIL and give other threads a
chance to run.
For some tests (eg `thread_coop.py`) the whole point of the test is to test
that the GIL is correctly bounced. So for those cases force the use of the
bytecode emitter for the busy functions.
