[xslt] Patch for Python bindings on MacOSX

Problem: the Python interpreter on MacOSX does not have the 'dl'
module, so the importing mechanism in libxslt.py does not have a way
to load the correct libxml2.dylib

I have made the attached patch, adding a special case (as there
already is one for Linux and Solaris). Now it works for me, but with a
consideration: the Apple-supplied python links against Apple's
libraries, which link to a libxml2.2.dylib

If libxslt were compiled against it, everything would work, but since
it probably is not (Apple gives no headers), I compiled both libraries
myself, and got segfaults. Now I invoke python with:

 $ DYLD_LIBRARY_PATH=/sw/lib python

since my libxml2 is in /sw/lib, it gets loaded instead of the
Apple-given one, and everything works.

Hope this helps.
