kill -s expects the signal name without SIG

The previous lxc-shutdown change replaced 'kill SIG<name>' by 'kill -s SIG<name>'. Although this works with busybox where it was tested, this doesn't actually work with all kill implementations. Some requiring just the signal name without the prefix. This changes "-s SIG<name>" by just "-s <name>". Tested with busybox and standard kill. Signed-off-by: Stéphane Graber <stgraber@ubuntu.com>
