dev.Dockerfile: allow skipping build of the web UI

We now run `make go-install-noui` and `make go-install-cli-noui` when
the `NO_UI` build arg is set to 1 to skip building of the web UI when
using the development docker container. If the `NO_UI` build arg is not
set, `make go-install` and `make go-install-cli` are run as before the
`NO_UI` build arg existed.
