fa858d63a0a5d794aab38c26f60c593513fe08de fuzz: Merge with -set_cover_merge=1 (MarcoFalke)

Pull request description:

  This should be less controversial than commit 151a2b189c3561dda2bb7de809306c1cfeb40e23. The overall size of the qa-assets repo is reduced further from 1.9GB to 1.6GB. Also, the runtime to iterate on the resulting folder is reduced further from ~1699s to ~1149s (N=1).
