wayland: import weston-launch setuid launcher
To run mutter as a display server, one needs to acquire and release the DRM master, which is only possible for root, so we take advantage of weston-launch, a small setuid helper binary written for the weston project. We import our own slightly modified copy of it, because weston-launch only launches weston, for security reasons. https://bugzilla.gnome.org/show_bug.cgi?id=705861
