get_filename : use the FILENAME field from the db.
 
This fixes FS#9547.

The get_filename function tried to construct the filename from name, version
and arch, instead of directly using the filename field from the database,
and got it wrong in most cases (with both core/extra and community repo).

Since this field was introduced in 3.0, it should be safe to use it now in
3.1.

Added a quick fix to pactest to also generate the FILENAME field in its sync
databases.
