qt4: package QML plugins and correct their install directory

QML components from Qt were installed to ${prefix} before and never got
packaged. This is now fixed and QML components are now installed into
${libdir}/${QT_DIR_NAME}/imports and packaged into qt4-*-qml-plugins
package.

Additionally qmlviewer and the examples/demos are now dependent upon
these plugins as needed.
