squalus 257db1dd4a nixos: systemd-coredump: improve disabled state
The systemd-coredump module required systemd to be built with
withCoredump=true, even if the module was disabled.

- allow systemd to be missing systemd-coredump if the module is disabled
- switch to mkDefault for the sysctl config to allow user overrides when
  the module is disabled
- add nixos tests for both the enabled and disabled cases
