fix incorrect list of sub-arches for aarch64
...
tests use older sub-arch that works in the older qemu

use an older arm64 sub-arch for test suite
...
hopefully this avoids the older qemu version crashing

aarch64: less feature-full baseline CPU

std.Target.CpuFeatures is now a struct with both CPU and feature set
...
Previously it was a tagged union which was one of:
* baseline
* a specific CPU
* a set of features
Now, it's possible to have a CPU but also modify the CPU's feature set
on top of that. This is closer to what LLVM does.
This is more correct because Zig's notion of CPUs (and LLVM's) is not
exact CPU models. For example "skylake" is not one very specific model;
there are several different pieces of hardware that match "skylake" that
have different feature sets enabled.
