Put the QML plugins to the non-config directory 

The generated qmldir files that are used by QML engine specify the
relative path to the QML plugins that are build within modules. So
it's usually expected that plugins are located on the same level as
the qmldir files. In Multi-Config builds all libraries are located in
the build-specific directories by default. In this case QML engine is
unable to locate the plugin and the application cannot be run without
extra manual steps. This fixes this issue, by using the top-level
plugin OUTPUT_DIRECTORY for the "default"(first) config as
RUNTIME/LIBRARY_OUTPUT_DIRECTORY.

In Windows platforms we need to make the same for non-static backing
libraries, since we cannot rely on RPATH there.
