MDEV-31231 fixes for MariaDB-connect-engine* rpms

* don't introduce random four-space-gaps into the middle of description
  (meaning, nicely aligned wrapped string in the code gets ugly
  in the rpm)
* remove obsolete comment
* MariaDB-connect-engine is a required package for MariaDB-connect-engine-jdbc
  not "recommended"
* don't recommend both mariadb-java-client and mysql-connector-java
* in fact, don't recommend anything, it works badly for old rpm < 4.13,
  installs something that user may not want, and install redundand deps.
  Let's rethink how to do it meaningfully. And not break tests.
