Remove mpris plugin

[TingPing]

It is a third party plugin that is causing crashes.

It is unfair to mpv to include it by default. This should go into an extension.

Closes #81

@TingPing there are no crashes because of mpris. Pablo is using mpv in cli or in a script, and using ctrl+c to exit it, session-bus is required for it to not throw error for SIGINT (ctrl+c). flatpak sandbox is not handling ctrl+c properly because of lack of --socket=session-bus, that's not a bug .

and an extension would be great, if you can make it, I tried but failed. finally someone thought of it after 10 monhts. https://github.com/fastrizwaan/mpv_extensions

No application needs session-bus permissions. There is just some bug in the plugin. It should never crash.

Remove mpris plugin

Please don't. It's not at all easy to put it back if the user wants it because of the difficulties in building a compatible .so file when the Freedesktop runtime has different library versions than the host distro.
