eds: Use new folks API for Google address book system groups

This removes the gigantic hack based on matching translatable strings across
gettext domains, and instead uses a new API from libfolks 0.7.2.

This requires EDS 3.5.2 at runtime (as it depends on a new vCard property
being exported by the Google Contacts backend), so its dependency has been
bumped as well. If the vCard property is not present, all Google contacts
will be considered _not_ in the “My Contacts” address book.

Closes: https://bugzilla.gnome.org/show_bug.cgi?id=676383
