Some programs of the `cdrtools` suite require certain special privileges to function properly - installing the `cdrtools` package from the Void repository, I'm not able to use for instance the `cdrecord` command obtaining "insufficient privileges" errors. It makes sense to me that it should be possible to use these commands as a normal user without requiring root access.

To achieve this without having to make the respective binaries SUID, [it is recommended](http://cdrtools.sourceforge.net/private/cdrecord.html) to make use of Linux capabilities. I have used the settings published in the [release notes](https://sourceforge.net/projects/cdrtools/files/AN-3.01/view) of `cdrtools` which is also what [Arch Linux does](https://github.com/archlinux/svntogit-community/blob/packages/cdrtools/trunk/cdrtools.install). The programs should be capabilities-aware and should drop the relevant privileges as soon as they are not needed anymore - some relevant discussion can be found [here](https://bugs.archlinux.org/task/67265) and [here](https://bugzilla.opensuse.org/show_bug.cgi?id=550021).

A patch file from https://github.com/void-linux/void-packages/pull/37640.patch is attached
