x86/boot: Grab kernel_info offset from zoffset header directly
Instead of parsing zoffset.h and poking the kernel_info offset value
into the header from the build tool, just grab the value directly in the
asm file that describes this header.
This change has no impact on the resulting bzImage binary.
