The motivation for dropping these translations is that we want to
avoid depending on intltool.

We tried to reimplement the translation functionality using `msgfmt`
from Gettext, for details see:
!29

It proved impossible to translate the 'DisplayName' field without
also having an unwanted translation of the 'Name' field. We could
work around this by switching to a different format, but we decided
these translations are of little importance as they don't appear in
the GNOME user interface, only in the output of our CLI tool
when `tracker daemon status` is run.
