Fix issue #97207 by filtering extension_list.cfg

The implemented solution to the problem of the error message
appearing when an excluded GDExtension in an export of a project, is
to filter the lines in the extension_list.cfg file to only include
those that are in the paths actually included for export.  If there
are no entries remaining, don't write the file at all.
