[kernel] add dummy HeapSetInformation()

[dank at vroo.pair.com]

This lets Black & White demo get further;
see http://bugs.winehq.org/show_bug.cgi?id=5694
My guess is this is relatively safe; HeapSetInformation
seems to be used to tweak heap properties for
performance.

Tested by running Black & White demo only.

Changelog:
  kernel/heap.c: add dummy HeapSetInformation()
