skins2: work around a deallocation problem

VlcManager and VarManager dependents on each other (a design problem)
Anyway, it is a bad idea to use instance() on any manager when deallocating ressources
as it can start anew a manager already deallocated.
Better use global variables in p_sys and act accordingly.
