mpg123: move all "extra" plugings to mpg123-sdl, rename to mpg123-extras
https://github.com/void-linux/void-packages/pull/41323

Description:
`mpg123-jack` introduces a build cycle, so let's minimize the dependencies of the base `mpg123` package by moving all "extras" to an `mpg123-extras` package that manages the individual subpackages. The `mpg123-extras` package can act as a meta that pulls in all the others.

**NOTE:** Because `mpg123-extras` isn't a real metapackage, `xbps-src` will refuse to create the package when it is empty, so fool the process by installing the `README`. I'm open to other ways to handle this problem, but it seems better that the template should be something generic instead of one of the arbitrary subpackages.
