use --mixer-linear-volume

[waschmittel]

First of all, thank you for an amazing install script. I'm effortlessly enjoying my music again :-)

There was one small hurdle: The raspotify service failed to start after reboot.

--linear-volume has apparently changed to --mixer-linear-volume

Oh, I just opened #88 without me noticing that you had already opened something pretty much similar.

But now I'm confused: Is --mixer-linear-volume or --volume-ctrl linear the right argument to use?
Maybe once dtcooper/raspotify#352 has been decided on, things will clear up.

[waschmittel]

According to librespot-org/librespot#447 --volume-ctrl linear should be correct. So I'll close this PR. :-)
