LP:330611 - test maria.maria fails if server built without '--with-partition'

Running the test maria.maria on a server built without the '--with-partition' configuration will result in a test failure:
maria.maria [ fail ]
Test ended at 2009-02-17 11:40:14

CURRENT_TEST: maria.maria
mysqltest: At line 1848: query 'alter table t1 partition by list (s1) (partition p1 values in (2))' failed with wrong errno 1289: 'The 'partitioning' feature is disabled; you need MySQL built with '--with-partition' to have it working', instead of 1526...

These results were a result of a BUILD/compile-pentium-debug build.

This is a simple fix and we can just add a --source include/have_partition.inc to have a graceful 'skip' in such a case (rather than a meaningless failure).

Also, do we want to alter BUILD files to include partitioning?
