[llvm] [llvm-exegesis][AArch64] Adding missing PR_PAC_ macro defintions (PR #138040)

[via llvm-commits]

https://github.com/zeroomega created https://github.com/llvm/llvm-project/pull/138040

This is a follow up of 3beacfa022da2a9c94e012e25bed89e8e4867ac2, which adds PR_PAC_APIAKEY macro to resolve the build failures on older Linux distros. However, it missed a few other definitions. This patch fixed this issue.

The defined values matches the linux header: https://github.com/torvalds/linux/blob/8bac8898fe398ffa3e09075ecea2be511725fb0b/include/uapi/linux/prctl.h#L227
