Merge #16569: Increase init file stop timeout

7fb7acfc20 Set init stop timeout to 10 min (setpill)

Pull request description:

  `bitcoind` can take a long time to flush its db cache to disk upon
  shutdown. Systemd sends a `SIGKILL` after a timeout, causing unclean
  shutdowns and triggering a long "Rolling forward" at the next startup.
  Disabling the timeout should prevent this from happening, and does not
  break systemd's `restart` logic.

  Addresses #13736.
