[gdm/wip/rstrode/wayland-filtering: 8/9] session: add property for ignoring wayland sessions

[Ray Strode <halfline src gnome org>]

commit 2607b326c18420649fa19970dfcb604d12867beb

    session: add property for ignoring wayland sessions
    
    We're going to want to be able to exclude wayland
    sessions from the search path if the manager deems it
    necessary.
    
    This commit adds a property to GdmSession to give the
    manager that ability.
