[do not merge] containerd/console is broken with current golang.org/x/sys

[thaJeztah]

As mentioned in docker/buildx#389

Needed to downgrade sys/unix with replace rule because the new one (that cli requires through moby/term) does not build with moby/moby and containerd/console. golang/sys@6fcdbc0 Moby isn't big issue as could be upgraded/removed but containerd package looks like a chunk of work (especially because on first look package itself does not seem to be implemented correctly)

opening this to discuss (not sure what the right fix/change is yet)

CI doesn't run on macOS, but this is the compile failure;

# github.com/containerd/console
./tc_darwin.go:33:31: undefined: unix.SYS_IOCTL

console/tc_darwin.go

Line 33 in af5b089

if _, _, err := unix.Syscall(unix.SYS_IOCTL, fd, flag, data); err != 0 {

This probably needs similar changes as were made in moby/term#16 @tklauser ?

Yes, looks like it. I've sent #40 with a fix.

let me close this one, now that #40 is up
