statically link libpython on macOS (#1105)

Statically link `python` to `libpython` on macOS. 

A dynamic `libpython` is still built and included in the distribution
for embedded use.

Remove patches that disable linking the libraries in statically linked
Python stdlib modules to python as these are now needed.

closes #636
