python/machine.py: Prohibit multiple shutdown() calls

If the VM is not launched, don't try to shut it down. As a change,
_post_shutdown now unconditionally also calls _early_cleanup in order to
offer comprehensive object cleanup in failure cases.

As a courtesy, treat it as a NOP instead of rejecting it as an
error. This is slightly nicer for acceptance tests where vm.shutdown()
is issued unconditionally in tearDown callbacks.
