get_enode.sh: --retry-connrefused instead --retry-all-errors

The `--retry-all-errors` flag was added only in Curl `7.71.0`:
https://github.com/curl/curl/commit/b995bb58

So it fails on older distrubutions with:
```
curl: option --retry-all-errors: is unknown
curl: try 'curl --help' or 'curl --manual' for more information
```
