Closed issue by b1scu1t on void-packages repository

https://github.com/void-linux/void-packages/issues/18976

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

* package:  
`dkms_2.8.1`

### Expected behavior
To be able to install `dkms` without requiring the `linux-headers` meta-package. 

### Actual behavior
The `linux-headers` meta-package is installed, even if kernel headers are already provided by another package. E.g: `linux-lts-headers`.

### Steps to reproduce the behavior
`sudo xbps-install -S dkms`

### Notes
As Void provides multiple kernels and kernel headers, I don't think it would be good to have dkms depend on one package in particular. I only use `linux-lts` and `linux-lts-headers`, but dkms will also generate modules for `linux`, which I don't have installed.
