make-dist: download liburing from kernel.io instead of github

Due to a bug with github.com, wget does not reliably download
packages. See https://github.com/orgs/community/discussions/65227

This change is motivated by this error that occurs when trying
to download liburing from github.com on an ubuntu jammy machine:
```
$ wget https://github.com/axboe/liburing/archive/liburing-0.7.tar.gz

```

The same does not happen on centos 8 or fedora.

Downloading from kernel.io works on every distro.
