* Let get_file_attributes() work without `lsattr -v`
Change:
- module_utils's get_file_attributes() expects `lsattr -v` to work, but
in some cases, it may not.
- The function now takes an optional include_version bool parameter,
which removes this expectation.
- Places where we call get_file_attributes() without using the 'version'
it returns, we now call it with include_version=False.
Test Plan:
- New unit tests
