neonvm-daemon: Use go-chef in Dockerfile

Probably an inadvertent merge conflict between #1090 and #989 meaning we
accidentally weren't using go-chef for neonvm-daemon.

Noticed this while developing locally and saw that it was re-downloading
all of the dependencies for neonvm-daemon every time, even though I was
making changes in the scheduler and the dependencies hadn't changed.
