The new Fremantle MicroB launching code breaks the assumption in the
microb script that the existence of the MicroB browser process implies
that MicroB is handling com.nokia.osso_browser. Revise the script to
check directly whether Browser Switchboard is handling that name, by
comparing its owner to that of org.maemo.garage.browser-switchboard
(using the org.freedesktop.DBus.GetNameOwner method).
