libnm: don't include "nm-version.h" in "nm-dbus-interface.h"

We want "nm-dbus-interface.h" to have no dependancy on libnm and glib.
That way, it is usable for example in the QT examples without dragging
in dependencies to glib.

Also drop all the unneccessary include to "nm-dbus-interface.h", which
we already get by directly or indirectly including "nm-core-types.h".
