unix: add SetsockoptTCPMD5Sig on linux

Browse Source 
This allows to set the TCP MD5 signature (see
https://www.rfc-editor.org/rfc/rfc2385) using TCPMD5Sig introduced in CL
106656.

Also export the storage data field in SockaddrStorage and convert it to
a byte array so the address in TCPMD5Sig.Addr can be set from an net.IP
without conversion.
