Migrate poiapp and libnaviapi-agl to AGL Gerrit
Update the poiapp and libnaviapi-agl recipes to point at AGL Gerrit for
their source repositories. Additionally, the libnaviapi-agl recipe has
been moved to recipes-demo/navigation since being beside its users seems
to be a more logical location, and a few lines have been reordered in
the poiapp recipe to better match the OpenEmbedded style guide.
