Assign externally open fd to gen_tcp (UDS support)
When a AF_LOCAL file descriptor is created externally (e.g. Unix Domain Socket) and passed to `gen_tcp:listen(0, [{fd, FD}])`, the implementation incorrectly assigned the address family to be equal to `inet`, which in the inet_drv driver translated to AF_INET instead of AF_LOCAL (or AF_UNIX), and an `einval` error code was returned. This patch fixes this problem such that the file descriptors of the `local` address family are supported in the inet:fdopen/5, gen_tcp:connect/3, gen_tcp:listen/2, gen_udp:open/2 calls
