cmake scripts: Do not add empty child conditions into condition list

Browse Source 
c.condition can be None, there is no point in adding it into the set of
conditions.
An example is tests/auto/corelib/codecs/qtextcodec/test.pro

Initializing the set to an empty set instead of None makes mypy happy,
since we could otherwise end up passing None where frozenset was expected.
