Bug#31314958 NDB_LIMIT_DEFERRED_TRIGGERS DEADLOCK TIMEOUT

The ndb_limit_deferred_triggers test executes update queries which are
intended to heavily stress the job buffers in the NDB data nodes. While
running these heavy queries on slower machines, the transaction deadlock
timeout will be triggered causing the queries to fail.

  CURRENT_TEST: ndb.ndb_limit_deferred_triggers
  mysqltest: At line 95: Query 'reap' failed.
  ERROR 1205 (HY000): Lock wait timeout exceeded; try restarting
transaction

Since test intentionally stressed the NDB data nodes towards its limits,
the system need to be configured appropriately to handle the load also on
slow machines. Increase the transaction deadlock detection timeout to
make the configured system more resilient.
