Make QtConcurrent compile in S60.

- Use clock() on Symbian for timing.
- Really don't use the STL when QT_NO_STL is defined.
  selectIteration decides how to iterate over the collection based on the iterator type
  (random access or not). Fall back to (potentially) slower forward iteration when
  QT_NO_STL is defined.

This isn't a complete fix, the compiler still gets confused by some of the map() overloads,
so QtConcurrent is still officially falls in the "Not supported" bin on S60.
