MBug#443014: Too many 'skipped' messages in mysql-test-run

Remove mysql-test-run.pl unnecessary and confusing 'skipped' messages.

 - In mysql-test-run.pl, we auto-generate combinations of replication
   tests. But this sometimes generates combinations that are meaningless,
   like running a test that requires row-based replication with
   statement-based. These superfluous combinationes should not be
   reported as skipped, they should just be deleted.

 - Remove ndb suites from default suites, as we do not support NDB
   in MariaDB.

Keep skip messages resulting from running mysql-test-run.pl in special
ways, eg. --mysqld=--binlog-format=statement.
