virsh: allow empty string arguments

"virsh connect ''" should try to connect to the default connection,
but the previous patch made it issue a warning about an invalid URI.

* tools/virsh.c (VSH_OFLAG_EMPTY_OK): New option flag.
(vshCommandOptString): Per the declaration, value is required to
be non-NULL.  Honor new flag.
(opts_connect): Allow empty string connection.
