rust-python-testing: separated base test classes

This will allow, e.g., to change `test-rust-discovery.py` simply
by adding the appropriate base class.

import sys

for line in sys.stdin:
    if line.lower() in ("message-id: \n", "in-reply-to: \n"):
        line = line[:-2]
    print(line, end="")
