[AArch64][GlobalISel] Exclude arm64 from failing tests (#178849)
As pointed out by the buildbots &
https://github.com/llvm/llvm-project/pull/174746#issuecomment-3821237987,
some of the tests modified by
https://github.com/llvm/llvm-project/pull/174746 are missing exclusions
for arm64 target triples causing the builds to fail.
I have added these exclusions here.
