lib/util/run_cmd: prevent zombies in samba_runcmd_send on timeout
Ensure the state desctructor calls tfork_destroy to reap the waiter and
worker processes. Otherwise we leave the waiter process as a zombie
behind us as we never call waitpid on it in case of a timeout
or talloc_free() from the caller.

winbind: Remove the use of "talloc_dict"
As members we only collect names, indexed by sids. This is served
well by just a simple dbwrap_rbt.
