Allow creation of Dockerfile.aarch64 through patch

When building an aarch64 docker image an Dockerfile.aarch64 file is
expected to exist. With this patch we may create it from the x86
Dockerfile by applying an aarch64 patch

This feature can be used with qtip, via
https://gerrit.opnfv.org/gerrit/#/c/30185/
