[dbus] Any user can own com.nokia.time name on SystemBus. JB#48473

In multiuser environment timed is not necessarily running as "nemo" user,
but still needs to be reachable by system services in SystemBus.

As D-Bus policy config does not support specifying currently active user,
allow any user in group "users" to acquire com.nokia.time service name.
