Trying to better use uncreat/zombie/orphan terms in tests

Renamed a bunch of tests:

- test_forphans_create_* -> test_forphans_uncreat_*
- test_forphans_cleanup_opened -> test_forphans_cleanup_open
- test_forphans_cleanup_orphaned -> test_forphans_cleanup_uncreat
- test_forphans_orphanzombie_fuzz -> test_forphans_uz_fuzz
- test_forphans_orphanzombiedir_fuzz -> test_forphans_uzd_fuzz
- test_*_oz_fuzz -> test_*_uz_fuzz
- test_*_ozd_fuzz -> test_*_uzd_fuzz
- test_traversal_*_orphan_* -> test_traversal_*_uncreat_*
- test_traversal_*_orphaned -> test_traversal_*_uncreat
- test_attrs_fattr_orphan -> test_attrs_fattr_uncreat

And renamed a number of variables and things.
