VOL-5352 - AWS AMI recreation

Makefile
--------
  o Define venv-name=.venv to fix a repo:onf-make transition issue.
  o Chicken-n-egg problem for git submodule checkout.
  o Cannot clone git submodules when a submodule provides the definition
    for venv-name.  Short lived problem, makefile-origin/ can be removed
    once the makefile has fully transitioned over to repo:onf-make library
    logic.
