Add needed lf-ansible and common-packer submodules

Latest version of global-jjb has the packer jobs starting to utilize
components from the LF releng/lf-ansible and releng/common-packer Gerrit
projects (also mirrored to GitHub). Neither of these projects has had an
official release so we're just going to the current head as the packer
jobs will fail if we don't have these in place now.
