s4 messaging tests: Fix race condition in smbcontrol tests
The test for the smbcontrol sleep command and the inject fault command
both used the "rpc_server" process as a target. As the inject fault
command caused the process to restart there was a race condition between
the process restarting and the sleep test running. To prevent this the
tests now use different target processes.
