tools-ctdb: Don't close stderr when running without_daemon commands

It looks like the original without_daemon code still tried to
establish a client connection to the daemon.  Closing stderr looks to
be a cheap way of hiding the errors when this failed.

However, later cleanups avoid the client connection altogether, so do
not close stderr.  Now debug output from without_daemon commands
actually appears.
