Although I don't really agree with the installing of the python bits to
the non-native paths, I can see where it's useful as long as the module
ABI doesn't change if you're trying to distribute binary tarballs.  But
with the current handling it adds module lookup costs for the native
path case (which would be the norm) as well as prevents using PYTHONPATH
to look to a different location for the modules.

The attached patch changes things so that at first, the xen module is
attempted to be imported from the stock paths.  If we get an ImportError
exception, then it adds /usr/lib/python to the end of the python path
and imports again.
