oss-fuzz: ensure base_copy is a generic-fuzzer

Depending on how the target list is sorted in by qemu, the first target
(used as the base copy of the fuzzer, to which all others are linked)
might not be a generic-fuzzer. Since we are trying to only use
generic-fuzz, on oss-fuzz, fix that, to ensure the base copy is a
generic-fuzzer.
