To pick up changes from:

  2d2123bc ("arm64/sve: Add prctl controls for userspace vector length management")
  7582e220 ("arm64/sve: Backend logic for setting the vector length")

That showed a limitation of the regexp used in tools/perf/trace/beauty/prctl_option.sh,
that matches only PR_{SET,GET}_, but should match a few more, like
PR_MPX_*, PR_CAP_* and the one added by the above commit, PR_SVE_SET_*.

This silences this warning when building tools/perf:

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

Support for those extra prctl options should be left for the next merge
window tho.
