Dockerfiles: Add git log when checking out from git

For all of the commands we run in dockerfiles where we check out code
from git, we should run `git log -1` so that in the logs of the docker
generation we can tell exactly which commit is checked out and in use
for that particular docker image, using only the docker build logs.
