Remove unused test utility files

These files are dead code - none of them are imported or used anywhere
in the test suite or the collection:
- tests/unit/compat/builtins.py
- tests/unit/mock/loader.py
- tests/unit/mock/path.py
- tests/unit/mock/procenv.py
- tests/unit/mock/vault_helper.py
- tests/unit/mock/yaml_helper.py
- tests/unit/modules/conftest.py
- tests/unit/modules/utils.py

Removing these files also addresses Python 2.7 compatibility concerns
raised in code review, as several contained deprecated imports that
would be incorrect to fix for Python 2.

Also removes corresponding pylint:ansible-bad-import-from entries from
tests/sanity/ignore-2.21.txt.
