    gsocks5proxy: Fix SOCKS5 username/password authentication
    
    It was checking for the main SOCKS5 version number, rather than the
    subnegotiation version number. The username/password authentication
    protocol is described in https://tools.ietf.org/html/rfc1929.
    
    Spotted and diagnosed by lovetox.
