rhythmbox: optionalise brasero
https://github.com/void-linux/void-packages/pull/22700

Description:
This PR adds a `build_option` for brasero and disables it by default. 

Note, `rhythmbox` from both [**Ubuntu**](https://packages.ubuntu.com/groovy/rhythmbox) and [**Debian**](https://packages.debian.org/sid/rhythmbox) repos doesn't have `brasero` as dependency. [**Arch Linux**](https://www.archlinux.org/packages/extra/x86_64/rhythmbox/) lists `brasero` as an optional dependency. But the one from Void repo pulls down `brasero` as hard dependency, which shouldn't be the case.
