selftests: net: py: color the basics in the output
Sometimes it's hard to spot the ok / not ok lines in the output.
This is especially true for the GRO tests which retries a lot
so there's a wall of non-fatal output printed.
Try to color the crucial lines green / red / yellow when running
in a terminal.
