Public bug reported:

On plucky, run:

root@plucky:~# localectl set-locale LANG=en_US.UTF-8
Failed to issue method call: Access denied

This is because of /usr/share/dbus-1/system.d/systemd-localed-read-
only.conf shipped in Debian and Ubuntu. This extra policy exists because
of incompatibilities between "Debianisms" like /etc/default/keyboard,
and more widely-adopted configurations like /etc/vconsole.conf.

In the case of locale, though, it seems relatively safe to allow on
Ubuntu systems. We have /etc/default/locale -> /etc/locale.conf, and
systemd-localed uses locale-gen as needed, which is what
locales.postinst does on install. Manual testing indicates that
localectl set-locale and update-locale play well together.

Furthermore, this restriction changes behavior that the desktop relies
on. Until a stronger reason can be demonstrated NOT to allow the
SetLocale dbus API to be used, we should remove the restriction.
