P2pool linux binary peer discovery errors - Ubuntu 20.04
Hello im back,

Environment 
Standard Ubuntu 20.04 - latest patch to date, 64bit
Node - Monerod - 0.17.30 official CLI

When i downloaded and run the latest p2pool v1.5 binary, the `peer_list.txt` is unable to find any peers. 
This also happened when i ran p2pool v1.4 the first time.
Supposedly, i should discover peers in syncing the sidechain process, but the `peer_list.txt` shows the following
```
0.0.0.0:37889
[::]:37889
```

I had to manually copy paste `peer_list.txt` from elsewhere into the binary directory, the everything would work.

I know my node is good, because i ran the same command using windows p2pool binary, it worked no problem and found peers.

Any suggestions in preventing this from happening?

I'm thinking keep an updated `peer_list.txt` on your @SChernykh github in case other people run into the same issue.

Thanks!
