Don't drop journalctl content if failure action is "shell"

Browse Source 
If failure action is set to "shell", user will need more debug info
available in kdump kernel. Especially when serial console is not
available, manually retrieve the log from journalctl is very useful
for debugging kdump issue.

Else, we can still drop journalctl content to save memory assuming
nothing will use it.
