selftests: tc-testing: test action batch deletion failure cleanup

Browse Source 
Add tests for cleanup after a batched RTM_DELACTION request fails at
a gact action bound to a filter. Check that subsequent actions retain
their original reference counts and that earlier successful deletions
are preserved.

Cover failures at the first and middle entries. Verify that a remaining
unbound action can be removed with one subsequent delete.
