mpv: use lib.generators to render config

Browse source 
There exist mpv configurations which cannot be expressed in
`programs.mpv.config` currently. For example, it is impossible to use
multiple 'profile' attributes. This commit changes the way config and
profiles are parsed, using `lib.generators.toKeyValue` and
`lib.generators.toINI`, to allow for these kinds of configurations
through the use of `listsAsDuplicateKeys`.
