Subject: [PATCH] Use gettext as fallback for translations

Upstream polkit action files do not necessarily contain translations for
all languages a distribution supports. And even if all translations are
contained in the head branch, distributions sometimes need to ship older
versions of packages. In order to allow retrofitting translations and
shipping language packs for polkit actions without having to patch and
rebuild packages gettext could be used as fallback. That way only
additional .mo files have to be installed.
So this patch makes polkit call into gettext with the domain
'polkit-action-distro-translations' if an xml doesn't contain
translations for the requested language.
