Update github.com/moby/term dependency to fix darwin builds

Description

I am trying to import the OpenTelemetry API into my project, but the build is failing on darwin with the following error:

# github.com/docker/docker/pkg/term
../go/pkg/mod/github.com/docker/docker@v1.4.2-0.20190924003213-a8608b5b67c7/pkg/term/tc.go:13:28: undefined: unix.SYS_IOCTL

It looks like this was fixed in github.com/docker/term a few weeks ago: moby/term#16

I'm guessing that moby/moby/pkg/term needs to be updated in vendor.conf to incorporate this fix
