gsocks5proxy: Fix SOCKS5 username/password authentication

Browse Source 
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.
