Enable `localtimed`, a simple daemon for keeping the
system timezone up-to-date based on the current location. It uses
geoclue2 to determine the current location.
To avoid silent overriding by the service, if you have explicitly set a
timezone, either remove it or ensure that it is set with a lower priority
than the default value using `lib.mkDefault` or `lib.mkOverride`. This is
to make the choice deliberate. An error will be presented otherwise.
