[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=552b4f9400d1710796371fb29c23087a78e5c440
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Systemd introduced a new policy described here:
http://lists.freedesktop.org/archives/systemd-devel/2011-March/001823.html

Add the "lock" group to buildroot to allow systemd to set this in place
at boot time
