If the owner of an object is taking a copy from the scene (e.g. via the "take copy" option on a viewer) then only require owner copy perms, not copy and transfer.

This matches Linden Lab behaviour and what was already possible via shift-copy.
Transfer would not apply here as the owner and copier are the same.
This is the only functional change, all other current take copy logic remains the same.
Adds regression tests around relevant take copy cases.
