Core dump message improvement (ATLASJT-401)

Improving message reporting for error exe65 with "Segmentation fault".

The "Segmentation fault" error message is already combination of parameters extracted after CoreDumpSvc from the log file. However, sometimes the message is not informative enough. One way to improve it, is to scan the log for abnormal activities happening before core dump and report them. As this abnormal lines do not have the standard logging format, in order to detect them, a "knowledge" file containing abnormal patterns is used as a reference. The abnormal line(s) together with the "last normal line" are reported to jobReport under the key "moreDetails" in addition to usual core dump message.
