jellyfin-media-player: disable pipewireSupport in mpv to fix segfault

Without this change it segfaults when trying to play any media:

  $ jellyfinmediaplayer
  Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
  libpng warning: iCCP: known incorrect sRGB profile
  Logging to /home/bf/.local/share/jellyfinmediaplayer/logs/jellyfinmediaplayer.log
  Cannot load libcuda.so.1
  Segmentation fault (core dumped)

The backtrace shows pipewire being at fault:

  $ coredumpctl debug

Standalone mpv doesn't segfault (when directly playing the underlying
media files). I don't know why.

Fixes: b97cda7 ("mpv-unwrapped: 0.34.1 -> 0.35.0")

Fixes NixOS#205141
