disable colorizer as it swallows fails
disable colorizer as it swallows fails

while the colorizer is pretty, it has the problem that fail output
actually gets completely swallowed when it is turned on.

Revert the use in run_tests.sh for now until it can be sorted out
so we don't prevent people from using run_tests.sh to do development.

Fixes bug #1159116
