fix(fls): Gnutella's peer limit is random in Java, not a default

PeerToPeerAnwendung's constructor rolls its peer limit (3, 4 or 5). The
getter defaults measured it once each run — 4, then 5 — and c48d15d
committed 5 as a default. GetterDefaults now constructs every class 64
times and writes a value that varies as {"random": [...]}; the decoder
answers a reference to it as unresolved, and the topology layer reports
a peer limit the file does not set as null.
