[PATCH 6/6] BaseTools/PatchCheck: Allow to print colored warnings

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

If the user has the termcolor package installed, and he configured
a 'color.checkpatch.error' color, use it to display colored warnings.

Example to display warnings in red:

  $ git config color.checkpatch.error red
