x86/cpuid: Include <linux/build_bug.h> in <asm/cpuid.h>

<asm/cpuid.h> uses static_assert() at multiple locations but it does not
include the CPP macro's definition at linux/build_bug.h.

Include the needed header to make <asm/cpuid.h> self-sufficient.

This gets triggered when cpuid.h is included in new C files, which is to
be done in further commits.
