Title: Fix for  "python setup.py --help"

In the current version, ``python setup.py --help`` leads to a traceback, due to setup_helpers triggering a bug (or perhaps feature?) in distutils. This patch gets around it by simply catching the exception distutils throws and continuing on with the astropy script.

This is quite simple, but I'm not entirely sure what this function is used for, so @iguananaut may want to glance at it before I merge it.
