Fix sporadic failure of rpl.rpl_parallel_innodb_lock_conflict

Browse Source 
Make sure the table mysql.gtid_slave_pos is altered to InnoDB before
starting parallel replication. The parallel replication of the suppression
insertion in the test case was trying to update the GTID position in
parallel with the ALTER TABLE, which could occasionally deadlock on the MDL
lock.
