By default, make KDE_INSTALL_USE_QT_SYS_PATHS share the same directory scheme as Qt if they share the prefix

Make Qt and ECM-based projects use the same directory sctructure (i.e. where plugins are, libs, etc.) by default. Otherwise it creates a tiny mess that might be controlled but usually won't.
In the end, otherwise, people need to keep adapting their systems with environment variables anyway. All distros end up setting always this setting as ON, as well as brave developers who don't have separate prefixes for Qt and KDE.
