Revert "[llvm-exegesis] Disable load store aliasing test"

This reverts commit 4efe170.

Not because I know it's working on AArch64 SVE, but because I
cannot reproduce it even on the same machine.

So in the hopes that it was a disk issue, something temporary,
I'm going to enable it again. If it fails again maybe it'll
show some sort of pattern or what I've missed to reproduce it.
