vga: fix byteswapping.
In case host and guest endianness differ the vga code first creates a shared surface (using qemu_create_displaysurface_from), then goes patch the surface format to indicate that the bytes must be swapped. The switch to pixman broke that hack as the format patching isn't propagated into the pixman image, so ui code using the pixman image directly (such as vnc) uses the wrong format. Fix that by adding a byteswap parameter to qemu_create_displaysurface_from, so we'll use the correct format when creating the surface (and the pixman image) and don't have to patch the format afterwards.
