g_error() is the wrong thing to do when, for example, we can't find the DRM device, since Mutter should just fail to start rather than reporting a bug into automatic bug tracking systems. Rather than trying to decipher which errors are "expected" and which not, just make all failure paths in meta_launcher_new() return a GError out to the caller - which we make exit(1). https://bugzilla.gnome.org/show_bug.cgi?id=757311
