autodoc: Removed autodoc directive from py swig

Since UPM uses doxy2swig, there is no need for the swig interface
file autodoc for python.

Also, turned on the doxy2swig --quiet switch which cleans up the build
log a tiny bit.

This removes a redundant chunk of documentation from python modules
(per each function).
