This commit improves ARM platform matching in two instances:
* Some old kernels reported the CPU architecture of arm64 cpus as
Aarch64 [1].
* In cases where the user is running with armv8 cpu and kernel but amrhf
user land (so armhf containerd), a possibility given the compatibility
of armv8 with armv7.
