Remove "Marketplace Package" from Drive package name on the Marketplace UI

On the Marketplace, Nuxeo Drive was called "Nuxeo Drive Marketplace Package". Since we're on the Marketplace, the "Marketplace package" is pretty obvious. I have manually renamed it in "Nuxeo Drive", but the original name was probably taken from https://github.com/nuxeo/marketplace-drive/blob/master/marketplace/src/main/resources/package.xml#L2. It should be edited so the title doesn't include this "Marketplace Package" part on the next release.
