um, hweight: Fix UML boot crash due to x86 optimized hweight
Apparently UML cannot stomach callee reg-saving trickery
introduced with d61931d89be506372d01a90d1755f6d0a9fafe2d
(x86: Add optimized popcnt variants) and oopses during boot:
http://marc.info/?l=linux-kernel&m=127522065202435&w=2
Redirect arch_hweight.h include from the x86 portion to the generic
arch_hweight.h which is a fallback to the software hweight routines.
