SO_REUSEPORT has gone from unix_impl

Operating system linux

Looks like constant SO_REUSEPORT has gone from linux impl.

libp2p/go-reuseport/impl_unix.go:47:51: undefined: unix.SO_REUSEPORT

The constant SO_REUSEPORT is still missing in Linux/386 and amd64. https://github.com/golang/go/issues/23696

Here is my Ubuntu system. I check go-1.10 and go-1.9.
