These message catalogs are specifically installed elsewhere in these scripts, and they should
be excluded from a find(1)-based discovery process.
Note that the order of discovery will vary depending on (at least) filesystem tyoe,
and so without this fix, the .mo files from gtk2_ardour/appdata could end up
overwriting the .mo friles from gtk2_ardour itself. This happened for the 8.11
release
