Subject: [PATCH] MT#66365 Add support for systemd-coredumpd from Debian forky

Starting with systemd v262 the coredumps are now handled by an active
service, instead of relying on the kernel piping them directly into a
program.

We need to update the expected core dump pattern, and also add a service
check to make sure the new daemon is running.
