Makefile (#3779): pass docker build arguments

Dockerfile requires some --build-arg options.
Fix "docker" target to pass them.
Fix GIT_TAG to reflect the most recent tag related to HEAD, instead of an unrelated most recent tag.
Use it as the image VERSION.

Image tags need to be passed explicitly if needed:

    DOCKER_FLAGS='-t erigon:latest' make docker
