Without this MR, elogind, and therefore weston will not start as it will
complain about cgroup mess:
[ 21.387150] elogind-daemon[1538]: Failed to determine whether /sys/fs/cgroup is a mount point: Symbolic link loop
[ 21.388341] elogind-daemon[1538]: Failed to mount cgroup at /sys/fs/cgroup/elogind: No such file or directory
Fix by applying this patch, thanks minlexx for pointing me to it! This
might possibly also be applicable to other kernel 3.4-based ports.
