tools headers: Synchronize kernel ABI headers wrt SPDX tags

Two more, that were just in perf/core and thus weren't covered by Ingo's
latest headers synch, kcmp.h and prctl.h, silencing this:

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