[PATCH BlueZ 1/1] tools/btmgmt: Fix btmgmt --help hanging

[Bastien Nocera <hadess@hadess.net>]

btmgmt when run interactively would wait for commands on its prompt, but
that prompt is never setup when the help output is requested.

Handle --help through bt_shell_handle_non_interactive_help() so that the
application exits as soon as the help content has been printed, like
other interactive apps in bluez.
