Fix some corner cases of condition mapping in pro2cmake

Browse Source 
no-png is an old unused scope that should be mapped to the png
feature instead.

Map contains(QT_CONFIG, shared) to correct variable check.

Sympy doesn't like dashes in indentifiers, so replace all of them
with a _dash_ token which will be replaced again at the end
of the condition simplifying.

When doing sympy preprocessing, fix mapping of target names that
don't contain double colons.
