fill_config.py: ignore templates starting with 'common_'

It's useful to include common parts in numerous cfg files, using the
${include(path)} command. So far they were called common_* and stored outside
of the templates dir (e.g. for logging). So far all files in a templates dir
are seen as templates, so the common files had to be stored in a different dir,
which is a bit senseless.

Allow storing them in the same dir with the templates: ignore all files
starting with 'common_'.
