There is some package-contains-documentation-outside-usr-share-doc that
are better to be there than move somewhere else. They are:
* mariadb-server: package-contains-documentation-outside-usr-share-doc [usr/share/mysql/errmsg-utf8.txt]
* mariadb-server-core: package-contains-documentation-outside-usr-share-doc [usr/share/mysql/charsets/README]
* mariadb-test: package-contains-documentation-outside-usr-share-doc [usr/share/mysql/mysql-test/README]
Also fix Mroonga
* mariadb-plugin-mroonga: extra-license-file [usr/share/mysql/mroonga/COPYING]
