ibusManager: Check existence of IBus systemd units before manual start

IBus is moving to being a systemd managed service in GNOME sessions
(see https://github.com/ibus/ibus/pull/2377). Since there will be a
transition period, and we still have to support non-systemd sessions,
check for this existence at runtime.
