cos-customizer: Add arm64 targets for some binaries

To support cos-customizer on arm64, some binaries that need to run in
the cos-customizer build VM need to have arm64 targets. We create arm64
targets and update references to use the amd64 targets for now, to
ensure that this change doesn't modify cos-customizer behavior.
