ZTS: Fix zpool_import_hostid_changed_unclean_export

Browse Source 
Update the test case to freeze the pool then export it to better
simulate a hard failure.  This is preferable to copying the vdev
while the pool's imported since with a copy we're not guaranteed
the on-disk state will be consistent.  That can in turn result
in a pool import failure and a spurious test failure.
