rabbitmq_ct_helpers: Make ignored crashes configurable

A testsuite just has to set:

    Config1 = rabbit_ct_helpers:set_config(
                Config,
                [{ignored_crashes,
                  ["some fixed string pattern A",
                   "some fixed string pattern B"]}
                ]),
