extensions: Pick up gettext domain from metadata

Since commit a6ee142f21, the extension archives that are uploaded
to extensions.gnome.org only contain strings that are relevant for
the extension, not all translations from all extensions.

Unfortunately all extensions still share a common gettext domain,
so the extension with the last bind_textdomain() call wins and
leaves the others without translations.

We'll address this by using distinct domains when not installed
system-wide. That becomes easier if there is a canonical place
for the text domain, with the existing metadata key being the
natural choice.
