[debian] build the book with no auto-compression of book files (closes: #1906581) Book content paths (html and rest) are now excluded from Debian compression step. This will fix a documentation search issue on the website (doc.cubicweb.org) Documentation build is now made optional since it can break for old distributions and we don't want to block a new release of Cubicweb because of documentation issues.
