 - Adjust timing in test case, to avoid test failures caused by high load
   on machines and consequent race conditions in the test case.

 - Add another variant of Valgrind suppressions for memory leak in system
   libraries when unloading dynamic object files.


mysql-test/r/information_schema.result:
  Adjust timing to avoid test failures due to races.
mysql-test/t/information_schema.test:
  Adjust timing to avoid test failures due to races.
mysql-test/valgrind.supp:
  Add another variant of valgrind suppression for leak in system libs.

query:
- When subquery is located in ORDER BY, EXPLAIN will run as follows:
  select_describe() will run JOIN::prepare()/optimize() for the subquery;
  then at some point subselect_single_select_engine::prepare() will be called,
  which will create another join and run join->prepare().

  In mainline mysql this is not a problem because subquery's join will be 
  destroyed after the first call. 
  In MariaDB, it won't (table elimination needs to keep JOIN objects around
  for longer in order to know which tables were eliminated when constructing
  EXPLAIN EXTENDED warning).

  Fix the problem of memory leak by calling select_lex->cleanup() in 
  subselect_single_select_engine::prepare().
