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:

The command builds were always using the root go.mod.
Adding cmd/mycmd/go.mod produced an "package not found" error.

This changes the build to run in the cmd/mycmd directory:
* If cmd/mycmd/go.mod is present, it is used.
* Otherwise it builds the main package using the root go.mod as before.

Refactor cmd targets to use a common implicit rule recipe.
Change "make all" to include them all.

Silence non-important comments in the "make erigon" output.
