Since the last time I ran this script, the Repology API changed, so I had to
adapt the script used in the previous PR. The new API should be more robust, so
overall this is a positive (no more grepping the error messages for our relevant
data but just a nice json structure).

Here's the new script I used:

```sh
curl https://repology.org/api/v1/repository/nix_unstable/problems \
   | jq -r '.[] | select(.type == "homepage_permanent_https_redirect") | .data | "s@\(.url)@\(.target)@"' \
   | sort | uniq | tee script.sed
find -name '*.nix' | xargs -P4 -- sed -f script.sed -i
```

I will also add this script to `maintainers/scripts`.

longDescription = ''
The libevent API provides a mechanism to execute a callback function
when a specific event occurs on a file descriptor or after a timeout
has been reached. Furthermore, libevent also support callbacks due
to signals or regular timeouts.
libevent is meant to replace the event loop found in event driven
network servers. An application just needs to call event_dispatch()
and then add or remove events dynamically without having to change
the event loop.
