description:
Correct discrepancy with the Multiboot specification

The VBE mode was missing, and the types of the subsequent VBE members
were also wrong. Nothing in NetBSD's base seems to be using this, and
therefore nothing is expected to break as a result of this fix, or any
binary to change for that matter.
The latest specification (as of today) can be found at:
https://www.gnu.org/software/grub/manual/multiboot/multiboot.html

This was already reported in misc/52366, and addresses part of it.

Patch sent to port-i386@. Build-tested on NetBSD/amd64.
