fix endianness problem sharing the videoram buffer
[ The following text is in the "UTF-8" character set. ]

[ Some characters may be displayed incorrectly. ]
This patch fixes vga rendering when the guest endianness differs from
the host endianness: in this case we can only share the buffer if the
bpp is 32 and we must change the pixelformat accordingly.
