tools headers UAPI: Sync prctl.h with the kernel sources



To get the changes in:

  1c101da8 ("arm64: mte: Allow user control of the tag check mode via prctl()")
  af5ce952 ("arm64: mte: Allow user control of the generated random tags via prctl()")

Which don't cause any change in tooling, only addresses this perf build
warning:
