packagegroup-qt5-toolchain-target: always include qttools packages

The qttools packages were included only if the ruby layer was enabled
as it required qtwebkit. However, qttools now has a PACKAGECONFIG
option for qtwebkit and does not enable it by default so we can include
the qttools packages even if the ruby layer is not enabled.
