New issue by kartikynwa on void-packages repository

https://github.com/void-linux/void-packages/issues/25795

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  `Void 5.8.16_1 x86_64 GenuineIntel uptodate hold rrrmFFFFFFFFFFFFFFF`
* package:  
  - `imlib2-1.7.0_2`
  - `feh-3.5_1`
  - `sxiv-26_1`

### Expected behavior
`feh`, `sxiv` should be able to open webp images since `imlib2` provides `/usr/lib/imlib2/loaders/webp.so`. For example, this should work:

```
curl https://www.gstatic.com/webp/gallery/1.webp | feh -
```

### Actual behavior
`feh` fails with the message: `feh WARNING: /tmp/feh_stdin_iWj0N5 - No Imlib2 loader for that file format`

### Steps to reproduce the behavior

```bash
xbps-install -Sf feh curl
curl https://www.gstatic.com/webp/gallery/1.webp | feh -
```

### Note

Installing [this](https://github.com/gawen947/imlib2-webp) makes it possible to open webp files. But it overwrites the `webp.so` installed by xbps.
