After-merge fixes for MySQL 5.1.41 merge into MariaDB: more fixes for Buildbot problems.

mysql-test/mysql-test-run.pl:
  Manually apply similar patch to the one in Bug#47983.
mysql-test/suite/rpl/r/rpl_temporary_errors.result:
  Fix wrong failure with warning in error log due to per-test suppressions
  not being active during server shutdown.
mysql-test/suite/rpl/t/rpl_temporary_errors.test:
  Fix wrong failure with warning in error log due to per-test suppressions
  not being active during server shutdown.
sql/sql_select.cc:
  Manually cherry-pick fix for Bug#45989.
  For some reason, that fix was reverted in MySQL 5.1, even though it is
  necessary to plug the memory leak.
