[mutter/wip/wayland-work: 14/25] Stop messing with process groups

[Giovanni Campagna <gcampagna src gnome org>]

commit 0b1d1bd555d8fe8aeb2fbf4301e98586f2f227c5

    Stop messing with process groups
    
    We can be launched by gnome-session now, which implies gdb must be
    attached from outside, and the Ctrl-C problem is gone.
