Bitcoin Core does not immediately use the fixed seed nodes if DNS seeding is disabled (-dnsseed=0) #19795

   Expected behavior: Disabling DNS seeding (-dnsseed=0) should make Bitcoin Core use the fixed seed nodes immediately on startup (assuming an empty peers.dat).

   Actual behavior: The fixed seed nodes are used but only after an unnecessary 60 second timeout, and a somewhat misleading log message (“Adding fixed seed nodes as DNS doesn’t seem to be available.”).

   To reproduce: rm ~/.bitcoin/peers.dat && src/bitcoind -dnsseed=0 and wait… 💤

   This issue is probably a “good first issue” :)
