Workaround for other object's DM build from modifier stack

Original issue is caused by dependency graph limitation,
which doesn't always give you other object's DM in such
modifiers as boolean and array. This might easily happen
when you render other scene from compositor,

Ideally, we need to make it so dependency graph is also
used in render database filling routines. This will also
solve issues with preview parameters used for boolean
operand as well.

For now let's use simpler change to make blender behave
stable at least by using CD_MASK_BAREMESH for other
object's derived final.

The thing is, handle_object_update will use baremesh mask
for derived mesh calculation and it seems baremesh is enough
for our purposes.
