OverrideValidation: Update logging levels (#450)

## Description
In scenarios where multiple track tags exist for a single library, only
one tag will match; previous logic would report this mismatch at a
logging.INFO level, which lead to developer confusion, thinking that
something needed to be fixed.

The logging level has been updated to logging.DEBUG for these messages.
errors are still properly reported when all tags do not match.

the RunCmd for returning the git commit has also been updated to
logging.DEBUG to reduce spam in the log as the commit hash returned from
the command is always printed later.
