[GRASS-stats] rgrass7: readVECT() issue with drivers other than ESRI Shapefile

No possibility of helping now, mostly offline to 8 August.
SQLite depends on the GDAL driver, which depends on an external library
(or several). The Windows and OSX rgdal binaries are built in as minimal
way as possible, linking statically. Adding SQLite possibly with
Spatialite is not currently feasible, and binary builds typically include
GEOS, which we don't want as it is used through rgeos, not rgdal. We
certainly should try to do something, but not by introducing any external
dependencies, so first check drivers available in the CRAN Windoes and OSX
binaries (which are built by the CRAN team, not me).
