tools headers: Synchronize kernel <-> tooling headers
Two kernel headers got modified recently due to meltdown/spectre, in:
a89f040fa34e ("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.
