gui: Fix compatibility with older gettext.

Older gettext does not recognize the metainfo.xml extension, only
appdata.xml.  This commit allows msgfmt to work with such older setups.

CC: Friedrich Beckmann <friedrich.beckmann@gmx.de>
Fixes: 86c5d611b3f2 ("metainfo.xml: changed id to org.fsf.pspp, added more information")
