x86: Add missing bzImage fields to struct setup_header

commit 37ba7ab5e3 ("x86, boot: make kernel_alignment adjustable; new
bzImage fields") introduced some new fields into the bzImage header
but struct setup_header was not updated accordingly. Add the missing
'pref_address' and 'init_size' fields.
