tools headers: Synchronize kernel <-> tooling headers

Two kernel headers got modified recently due to meltdown/spectre, in:

  a89f040 ("x86/cpufeatures: Add X86_BUG_CPU_INSECURE")

which are used by tooling as well:

  arch/x86/include/asm/cpufeatures.h
  arch/x86/include/asm/disabled-features.h

None of those changes have an effect on tooling, so do a plain copy.
