Revert "Clean up usage of qtsvg as dependency"

qtdeclarative has a runtime dependency, some tests rely on the svg
module being available, so in order to not reduce the test coverage,
revert this change.
I'd like to see a better/cleaner separation, but for the time being,
better coverage wins.

This reverts commit fbd782636b.
