Richard Heck f9de88c53c Remove the shebang line from our python scripts, per Jose's suggestion.
Fedora ships these chmod 644 and has never seen a problem. The advantage
to doing this is that it better controls what version of python we are
using to launch the script, and it will reveal if we're somehow somewhere
not controlling that properly.
