Invalid detect-engine config could lead to segfault

Description

Certain invalid YAML configs for the legacy detect-engine config node can cause a segfault. The following config node can reproduce this when launched with -T:

detect-engine:
  custom-values:
    toclient-groups: 200
    toserver-groups: 200

This is caused by a strcmp on line 1873 in detect-engine.c, where opt->val is null for the custom-values node:
