target-i386: add kvm stubs to user-mode emulators

Browse Source 
The CPUID code will call kvm_arch_get_supported_cpuid() and, even though
it is undef kvm_enabled() so it never runs for user-mode emulators,
sometimes clang will not optimize it out at -O0.

That could be considered a compiler bug, however at -O0 we give it
a pass and just add the stubs.
