Resolve demos and examples also relative to qt install paths.

Browse Source 
Qt5 has the manifest files in QT_INSTALL_DOCS but the actual examples in
QT_INSTALL_EXAMPLES/DEMOS, which can be completely independent.
The patch tries to resolves files relative to the manifest, and if that
fails, relative to the install paths.
