Fixed failing test cases

mysql-test/include/have_not_innodb_plugin.inc:
  Also detect if xtradb is installed
mysql-test/suite/innodb/t/innodb_bug56143.test:
  Disabled test case that doesn't work for innodb_plugin/xtradb.
mysql-test/suite/innodb_plugin/r/innodb_bug56632.result:
  Updated result (key_block_size is lower case in MariaDB, as all other options)
mysql-test/suite/pbxt/r/partition_hash.result:
  Updated results (after partition row count optimization changes)
mysql-test/suite/pbxt/r/partition_pruning.result:
  Updated results (after partition row count optimization changes)
mysql-test/suite/pbxt/r/partition_range.result:
  Updated results (after partition row count optimization changes)
mysql-test/suite/pbxt/r/subselect.result:
  Updated result after ROW() changes.
