Revert "Base our SourceHut CI builds on Docker."

Running the Dockerfiles in CI seemed like a good idea, but I'd forgotten that
they pull from the master branch, rather than using local source. Could be
reinstated if we make Dockerfiles use local source as discussed in trac#5574.

This reverts commit 712728c331.
