1. conf: fix NULL-pointer dereference in CoredumpLoadConfig …

   An empty value for coredump.max-dump in the config-file leads to a segfault because of a NULL-pointer dereference in CoredumpLoadConfig().
   
   Here is a configuration example:
   
   coredump.max-dump: []
   
   This lets suricata crash with a segfault:
   
   ASAN-output:
