cluster/images/hyperkube: re-add hyperkube busybox style symlinks

Originally symlinks were added with a `--make-symlinks` command discussed in https://github.com/kubernetes/kubernetes/issues/24510 and implemented in https://github.com/kubernetes/kubernetes/pull/24511.

It was backed out in https://github.com/kubernetes/kubernetes/pull/25693 because go binaries don't run in qemu and this breaks cross-building the Dockerfile for arm. In this case, due to running `hyperkube --make-symlinks`.

Lets just add the symlinks manually until the upstream bug is fixed (qemu).

fixes #28702
