KVM: x86: use a separate asm-offsets.c file
This already removes an ugly #include "" from asm-offsets.c, but
especially it avoids a future error when trying to define asm-offsets
for KVM's svm/svm.h header.
This would not work for kernel/asm-offsets.c, because svm/svm.h
includes kvm_cache_regs.h which is not in the include path when
compiling asm-offsets.c. The problem is not there if the .c file is
in arch/x86/kvm.
