Subject: [PATCH v1 04/40] x86/cpuid: Include linux/build_bug.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.

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

Fixes: 43d86e3cd9a7 ("x86/cpu: Provide cpuid_read() et al.")
