[Kernel] Retain handles and not objects in XThread 

This fixes cases introduced by 52e836d0f8
where thread handles get closed before the thread finishes.
Handle was assumed to be alive there, which was not true as
threads self-referenced only their objects, not their handles.

Affected games: Payday 2 Demo
