Drop prebuilt images; allow build without `executors/docker/bindata.go`
Using pre-built images incorporated into executors/docker/bindata.go
strikes me as incredibly sloppy.
Also this approach is incompatible with Debian policy.
Downloading on build-time is prohibited in most (sane) build environments.
It should be possible to build GitLab Runner without bindata.go
,
with proper dependencies on Docker (and other packages/daemons) as required.
