Set init stop timeout to 10 min

`bitcoind` can take a long time to flush its db cache to disk upon
shutdown. Most init files send a `SIGKILL` after a timeout of 1 minute,
causing unclean shutdowns and triggering a long "Rolling forward" at the
next startup. Increasing this timeout to 10 minutes should reduce how
often this occurs, especially during IBD.

fixup! Set ProtectHome in systemd service file
