KVM: selftests: Stash backing_src_type in struct userspace_mem_region 



Add the backing_src_type into struct userspace_mem_region. This struct
already stores a lot of info about memory regions, except the backing
source type.  This info will be used by a future commit in order to
determine the method for punching a hole.
