fix(dev-lang/python-oem): cleanups and fixes for OEM python

Remove all RDEPENDS, OEM packages are installed after prod images are
pruned of the previously installed package database.

Re-enable XML and ctypes support since the required libraries happen to
be bundled with Python.

Assorted other simplifications.
