UTIL: Introduce --dbus-activated cmd option for responders

Similarly to the --socket-activated cmd option, --dbus-activated cmd
option is going to be used for dbus-activated responders in order to
easily setup a timeout to shutdown the idle responder in case it has
been socket activated and is idle.

This option has been encapsulated on is_dbus_activated() function,
which will always return "false" when called on platforms where systemd
is not supported.

For now any of the services are taking advantage of this newly
introduced option/function, but later on in this series it's going to be
used.

In order to use it, just add SSSD_RESPONDER_OPTS to the poptOption
structure.
