Alpine is the base docker image for the LinuxKit, but currently it only supports amd64 architecture. This patch is try to unify the alpine tool docker image build process order to suport other architectures, such as AArch64, by using '--build-arg' to override the alpine base image specified by 'FROM' in the Dockerfile. Also this patch splits the standalone packages into 2 parts: one is common for all archs, another is arch-specific. Signed-off-by: Dennis Chen <dennis.chen@arm.com>
