Subject: [PATCH] Capture core dump files from tests (#123169)

When running Elasticsearch in tests we occassionally have JDK crashes.
It's important to capture the state of the JVM at the time of the crash.
We currently capture the hs_err_pid file for the crash, but the
resulting core file exists in a directory that is no captured. This
commit adjusts the capture patterns to also get core files.
