Michael Brown 90563f69be [prefix] Set the "size" bit in the GDT entry for the flat data segment ...

The "size" bit (aka the D/B) bit should (as far as I can tell) be
irrelevant for accesses to a non-code, non-stack, expand-upwards
segment.  However, VirtualBox fails on some accesses via this segment
if this bit is not set.

This change allows iPXE to boot under VirtualBox without having to
disable VT-x/AMD-V support.
