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

To get the changes in:

  1c101da8b971a366 ("arm64: mte: Allow user control of the tag check mode via prctl()")
  af5ce95282dc99d0 ("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:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/prctl.h' differs from latest version at 'include/uapi/linux/prctl.h'
