Add support for additional library paths to the MapViewer example

This patch makes the MapViewer example fetch and add additional
library paths from the environment variable
"QTLOCATION_EXTRA_LIBRARY_PATH".
This path is colon separated, and can be used to add and test additional
plugins easily, without the need to modify the example.
