change shutdown level for ctdb to be 01

We want ctdb to shutdown first, as it manages many other
services. With the old level of 32 the NFS service would shutdown
first, and that would trigger ctdb to do a recovery. Then ctdb itself
would be shutdown a few seconds later, which causes a lot of error
messages in the other nodes logs

(This used to be ctdb commit 2f952af1a12e81a652ec9a4794db96f9593f2676)
