examples/topology: define socketIds and siblingsIds as sets

Browse Source 
socketIds and siblingsIds are declared as empty lists, filled by
list comprehensions, and later on re-used as sets.

They could be directly obtained from set comprehensions.

Fixes: 34aa32b ("Move python example programs into python/examples/ subdirectory")
Fixes: 3f4e32c ("examples: Invoke print("...") instead of print "..."")
