Add BRANCH as Docker build arg

It conforms with the prerequisite of the current releng Docker script.
BRANCH can be considered as useless because releng already clones the
right git branch.

It's a temporarily solution before modifying a script used by lots of
OPNFV projects.

Conflicts:
    docker/components/Dockerfile
    docker/healthcheck/Dockerfile
