Rename PyInit syms to avoid clashes

Built extensions in packages often have common names
like speedups, utils, _objects, cpython, etc. which
reside inside the package namespace.
The compiled extensions each have a PyInit_<module>
which needs to be renamed to PyInit_<pkg>_<module>
to avoid clashes when combined into a static binary.

Fixes #169
