    xen/version: Fold print_build_id() into print_version()
    
    Both callsites call them as a pair, and more generally, anyone wanting the
    changeset wants the buildid too.
    
    This involves rearranging console_init_preirq() to ensure xen_build_init() 
is
    ahead of print_version().
    
    No functional change.
