x86/uapi: Stop leaking kconfig references to userspace

Browse Source 
UAPI headers are not supposed to leak references to kconfig symbols.
These won't be set when building userspace. Hide the kconfig reference
behind 'if defined(__KERNEL__)', so it will be stripped by
headers_install.sh. The result for userspace will be the same, but the
exceptions in headers_install.sh can also be removed.
