cmd/uplink: add docker image

Add a docker image for uplink-cli and push it to docker hub.
We used to have this before the change to uplinkng. I'm not
sure if the pushing works, we'll see after merge.

To test, build an image with `make uplink-image`, read the tag from the
output and run normal uplink-cli commands using
`docker run -it storjlabs/uplink:df9bbceca-uplink-docker-go1.18.8-amd64 [command]`

Part of storj/uplink#109
