Removing git-objects, which are not needed, from final docker image, to make it
smaller. Some files still need to be there, because Etherpad at startup uses
them to discover its version number.
With this change, the Dockerfile builds the Docker image from the code
checked out in the local filesystem, instead of downloading a revision
from git.
Implements #3657
