MPV MPRIS plugin fix
https://github.com/void-linux/void-packages/pull/24285

Description:
mpv and the mpv-mpris plugin weren't working together out-of-the-box for me, so these edits fix that.

I've confirmed on my end that these changes work :)

The changes made are based on the documentation for mpv-mpris [here](https://github.com/hoyon/mpv-mpris).
