[FIX] packaging: fix rpm package and stop using bdist_rpm

The rpm package failed recently on a file name containing a space.
This issue is fixed by protecting file names with double quotes in the
installed files list.

Also, during this fix, it was discovered that the bdist_rpm is
deprecated in setuptools [0].

For that reason, the rpm is now generated from the package.py script.
