[telepathy-gabble/master] Run test-debug.py if the debugger is enabled, using an automake conditional

[Simon McVittie]

The Makefile rule that generates tests/twisted/config.py was always
setting DEBUGGING = False there, because ENABLE_DEBUG was not in fact
set in the Makefile.

Based on a patch from wjt.
