GetFeature returns a content-length header which does not include the length of the content returned after the '<wfs:FeatureCollection>'-element.

Some clients dont accept content beyond the content-length and these clients will hence see an empty (and malformed) FeatureCollection.

This may relate to #13182

Example executing qgs_server from cli:

~/qgis-install/QGIS.app/Contents/MacOS/fcgi-bin
$ QUERY_STRING="map=/Users/asger/Code/QGIS-server-content-length/qgis-server-content-length.qgs&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&TYPENAME=data&SRSNAME=EPSG:4326&BBOX=-90,-90,90,90" ./qgis_mapserv.fcgi
