cubicweb-skos #7418097 Send correct content-type header when exporting to RDF [validation pending]

Official media type for RDF/XML is application/rdf+xml (see http://www.w3.org/2002/06/registering-mediatype2014.html).

Moreover, rdflib, only recognize application/rdf+xml.

So when exporting RDF data, content-type in response header should be set to application/rdf+xml (instead of the current text/xml)
