[Buildroot] [PATCH] gpsd: dbus interface requires dbus-glib

[Arnout Vandecappelle (Essensium/Mind)]

gpsd uses dbus-glib as the dbus interface, so it should only be built if
libglib2 has been selected.  To simplify things, build dbus support only
if dbus-glib is selected.

v2:
The select of DBUS_GLIB in Config.in created a circular dependency.  So
I simplified things by looking at DBUS_GLIB instead of DBUS for automatic
enabling of dbus support.

Also added help text to explain this.
