WFS 2.0 wrong extension response to a spatialite zip request

[aperi2007]

Mapserver use wrong extension in a response to a spatialite zipped request.

Starting from this setting:

OUTPUTFORMAT
NAME "SPATIALITE"
DRIVER "OGR/SQLITE"
MIMETYPE "application/zip"
FORMATOPTION "DSCO:SPATIALITE=YES"
FORMATOPTION "STORAGE=memory"
FORMATOPTION "FORM=zip"
FORMATOPTION "FILENAME=result.db.zip"
END

The zip resulted will not contain a file .sqlite but instead a file with zip extension.
But this is not a zip file.It is instead a real spatialite db. The MapServer has named its extension .zip instead of .sqlite

the FILENAME key is used to create the OGR datasource, so it should probably be set to result.db instead of result.db.zip. However when using zipped form, we should probably append ".zip" to the filename of the Content-Disposition header. cc @rouault

@tbonfort I will take after this bug. My intent is, when FORM=zip, to analyse the filename. If it is of the kind foo.bar.zip, then the OGR datasource will be created with foo.bar as a name, and the result will be zipped in foo.bar.zip. If FILENAME is not specified or just as foo.zip then the OGR datasource will be named result.dat.

I believe that this one can be closed like the referenced #4856.
