Fix shader file loading in qmlvideofx example

Each effect is implemented as a QML element, whose
fragment/vertexShaderFilename properties specify paths from which
shader programs are loaded.  These paths are relative to the application
installation directory, e.g. "shaders/billboard.fsh".  If the current
directory from which the application is launched does not match the
installation directory, shader program loading fails.  This patch
converts the relative filename provided by the QML element into an
absolute path before attempting to open the file.
