scripts: ci: check_compliance.py: Fix perl script running on windows

Add an if clause to the CheckPatch Class that checks for windows os.
If windows os, check for perl installation.
If no perl installation present. Fail the check.
Without this change, CheckPatch can fail silently on windows,
as windows does not have a way to run perl scripts.
