[PATCH v2 17/25] tests/functional: give the set_machine probe VM the test workdir

set_machine() launches a throwaway QEMUMachine to query the available
machine types, but constructs it without base_temp_dir, so it falls back
to the hardcoded "/var/tmp" default instead of the writable per-test
workdir that the actual test VM already uses. Pass base_temp_dir=
self.workdir for consistency; this also fixes VM launch on hosts where
/var/tmp is not writable.
