Some of the packages that provide the core-dump-handler virtual package
(corekeeper, minicoredumper, systemd-coredump) store the saved core
dumps in defined locations.

When no core dumps or other files are specified, it would be helpful if
find-dbgsym-packages could select all the core dumps in each of the
following locations. This would easily allow installing the right debug
symbols for all recent crashes.

systemd-coredump stores them in paths with this wildcard:

   /var/lib/systemd/coredump/core.*.*.*.*.*.zst

corekeeper stores them in paths with these wildcards:

   /var/crash/*/*.core (Linux)
   /var/crash/*.core (kFreeBSD)

minicoredumper stores them in the base_dir directory listed in its JSON
based configuration file and names them with this wildcard *.*.*

   /etc/minicoredumper/minicoredumper.cfg.json
