[egg-list-box] Make egg_list_box_set_sort_func() usable from gjs

[Carl-Anton Ingmarsson <carlantoni src gnome org>]

commit 035666d2d5892e75315b56fd27ceb478d700ec17
Author: Carl-Anton Ingmarsson <ca ingmarsson gmail com>

    Make egg_list_box_set_sort_func() usable from gjs
    
    Add a new function signature with explicit pointer types and annotate
    egg_list_box_set_sort_func properly.
    
    WARNING: This changes the signature of the sort function which may cause
    new warnings for modules that currently passes a GCompareDataFunc.
