[QGIS-Developer] Docs Travis, Failed to open /usr/share/qgis/resources/data/world_map.gpkg: Permission denied.

[Richard Duivenvoorde]

Hi Devs,

A build of a Docs PR of my [0] in which I try to open the world_map.gpkg is failing because:

Warning 4: Failed to open /usr/share/qgis/resources/data/world_map.gpkg: Permission denied.

In my local builds 

iface.addVectorLayer(os.path.join(QgsApplication.pkgDataPath(),'resources','data','world_map.gpkg|layername=Countries'), '', 'ogr')

just works.

But in Travis (and a global install) apparently the resources are not readable by a normal user.

What could be the best solution for that:
- add an install step which makes such resources available for users (and their plugins?)
- create code so the inbuilt: uri's would work (see [1])
iface.addVectorLayer('inbuilt:/data/world_map.gpkg|layername=countries', 'Countries', 'ogr')

Any input appreciated, Thanks,

Richard
