scripts/oss-fuzz: ignore the generic-fuzz target

generic-fuzz is not a standalone fuzzer - it requires some env variables
to be set. On oss-fuzz, we set these with some predefined
generic-fuzz-{...} targets, that are thin wrappers around generic-fuzz.
Do not make a link for the generic-fuzz from the oss-fuzz build, so
oss-fuzz does not treat it as a standalone fuzzer.
