Windows fixes

Created by: SchrodingersGat

This PR makes some subtle changes to the checklib.py and check_kicad_mod.py scripts to allow them to work better under windows.

• Enable wildcard support - Windows does not have command-line wildcard support by default.
• Fixed reference to print_color.py in check_kicad_mod.py - Python under windows doesn't support running external scripts in this fashion.

Please check that both of these scripts still perform as intended under *nix
