If RIO is unavailable, NewWinRingBind() falls back to StdNetBind.
StdNetBind uses x/net/ipv{4,6}.PacketConn for sending and receiving
datagrams, specifically via the {Read,Write}Batch methods.
These methods are unimplemented on Windows and will return runtime
errors as a result. Additionally, only Linux benefits from these
x/net types for reading and writing, so we update StdNetBind to fall
back to the standard library net package for all platforms other than
Linux.
