Plug remaining leaks in tests/auto/widgets/kernel

The usual:

- delete return values of QLayout::takeAt(), replaceWidget()
- delete styles
- delete top-level widgets
- delete actions

Either by naked delete, QScopedPointer or allocation on the
stack instead of the heap.

This fixes the remaining errors in GCC 6.1 Linux ASan runs of
tests/auto/widgets/kernel.
