Subject: [PATCH] x86/head: Simplify #include "../../x86/xen/xen-head.S"

Since `kernel/head_32.S`, `kernel/head_64.S`, and `xen/xen-head.S` are all
located in the same `arch/x86` directory, when `kernel/head_32.S` and
`kernel/head_64.S` want to include `xen/xen-head.S`, we can directly use
the `#include "../xen/xen-head.S"` directive rather than the more verbose
`#include "../../x86/xen/xen-head.S"` directive. They point to the same
file.
