test-debugextensions: add dummy extension to make ifcontains() test more solid

If testedwith were a string, ifcontains("3.2", testedwith) would match "3.2.1".
New test added to cover that.

# showstack.py - extension to dump a Python stack trace on signal
#
# binds to both SIGQUIT (Ctrl-\) and SIGINFO (Ctrl-T on BSDs)
