driconf: Fix gen_xmlpool.py script to allow running from any directory

The gen_xmlpool.py script would work correctly only when executed from the
directory that contained the script. This shortcoming was due to some
hard-coded paths in the script.

In order to easily invoke the script from the Android build system, we
must be able to execute the script from an arbitrary directory. To enable
that, this patch replaces the two hard-coded paths with new command line
arguments.
