Write test for ownership of file.managed with makedirs=True
Add tests for #12209
Use custom user/group for integration tests for #12209

to use a "test12209" user/group for these tests.
Use new decorators for issue 12209 tests
Add skipIf and destructiveTest

These tests must be run as root, and create and destroy a user and
group, so this adds the proper decorators.

Additionally, this wraps the assertions from these tests in a try/except
block that ensures that the temp directory created for this test is
cleaned up.
Fix import
Remove unnecessary except
