sys: remove socketpair for AF_INET and AF_INET6

* OpebBSD: remove socketpair() for AF_INET and AF_INET6.

socketpair() is only supported on AF_UNIX.

* NetBSD: remove socketpair() for AF_INET and AF_INET6.

socketpair() is only supported for AF_UNIX.

* FreeBSD: remove socketpair() for AF_INET and AF_INET6.

socketpair() only supports AF_UNIX.

* Linux: remove socketpair for AF_INET and AF_INET6.

socketpair only supports AF_UNIX.

* Autogenerated files.

These are manually generated for all platforms you are not
running on. FreeBSD in this case.

* executor: rebase.

* sys/freebsd: rebase.

* sys/linux: use AF_UNIX based socketpair for nbd.

This was suggested by Dmitry.

Fixes #845
