ctdb-scripts: Use nfsconf as a last resort get nfsd thread count

Browse Source 
If nfsconf exists then use it as last resort to attempt to extract
[nfsd]:threads from /etc/nfs.conf.

Invocation of nfsconf requires "|| true" because this script uses "set
-e".  Add a stub that always fails to at least test this much.
