internal/socket, route: drop support for pre-1.12 direct syscalls on darwin
Go 1.12 and newer are using libSystem for syscalls on darwin.
Go 1.11 is the last release to use direct syscalls. It hasn't been
supported since the release of Go 1.13 in September 2019, so drop
support for direct syscalls on darwin from golang.org/x/net.
