[glabels/glabels_2_2] Add place-holder field to all empty private structures

    Add place-holder field to all empty private structures
    
    Fixes glabels bug #2981895.  This is a work-around for glib bug #615379.  For
    objects with no private data, add a place-holder field so that the private
    structure is not of zero length which causes g_new0() to crash in glib
    2.24.0.
