vgabios: Make sure exported structs use PACKED.
Commit ca668640 introduced structs for data returned from the
handle_101b and handle_101c calls. However, the structs were not
declared as packed and that caused incorrect behavior for
handle_101b. This was seen to break some old DOS programs (Win3 setup
and DISPLAY.SYS). This patch adds in the necessary PACKED declaration
to the structs.
The 'struct saveBDAstate' remains un-packed, as it does not appear
that its contents are documented. (And, its format already differs
from what was in the previous "lgpl vgabios".)
