wutil: Missing --hidden flag in the usage (-h) output

[Defenso-QTH]

Running wutil -h does not show the --hidden flag that is mentioned in the manpage.

[MainKt]

The -h option when used after connect sub-command is shorthand for --hidden, currently wutil only prints short options for usage (^_^;)

$ wutil -h
Usage:  wutil {-h | subcommand [args...]}
...
        wutil [-c <wpa-ctrl-path>] connect
          [-i <eap-id>] [-p <password>] [-h] [-f <freq>] <ssid> [password]
