[capi-sig] Garbage output from warnings with embedded python

[Campbell Barton]

had another look into it and figured out whats going on, in short for
warnings python wants there to be a file on disk for the script and in
our case there is None, its not getting __file__ from the global
namespace so it gets argv[0] which is the blender3d binary in our
case.

The only fix I found so far was to set the __file__ variable in the
namespace before running the script.
