py3: split check of pygments-using files from the rest of the tree
If we don't do this, people without pygments installed in their Python
3 environment silently stop checking test-check-py3-compat, which
isn't really what we wanted. This preserves stability of the test
output while still letting anyone with a recent-enough Python 3 run
the majority of the Python 3 compat checking test.
