logging the crash properly when running test262-harness.py (#4472)

When running tests262 cases, the jerry program may exit with error code other than 1,
that's means a crash or JERRY_ASSERT triggered and should be resolved, so dump the test
name and stderr/stdout for tracking those crash in CI.

related issue: #4463
