ovs-sandbox: Show the running program on xterm's title

When debugging multiple programs under GDB, it will be easier to
identify xterms with the program name displayed as title. Without
this patch, xterms will have the title of "gdb", which is the first
program the xterm executes. This change is useful for the next patch.
