In case of exhausting FD limit the diffusion ought to shutdown

Our current [`RethrowPolicy`](https://github.com/input-output-hk/ouroboros-network/blob/master/ouroboros-network/src/Ouroboros/Network/Diffusion/P2P.hs?plain=1#L1117-L1124) (for P2P) and `ErrorPolicy` (non-P2P, both [`remoteNetworkErrorPolicy`](https://github.com/input-output-hk/ouroboros-network/blob/master/ouroboros-network/src/Ouroboros/Network/NodeToNode.hs) and [`localErrorPolicy`](https://github.com/input-output-hk/ouroboros-network/blob/master/ouroboros-network/src/Ouroboros/Network/NodeToNode.hs?plain=1#L663)) will only shutdown the peer that exceeded the file descriptor limit.
