ksys/gdt: Make ~Manager the key function to help with dtor matching

Make syncData a pure virtual function that is overridden in Manager
to turn the destructor into the key function.

Otherwise, the GOT would be used to load the vtable pointer until
syncData is implemented, which is quite inconvenient.
