Modified from upstream commit:
https://github.com/ankitects/anki/commit/ccd715013609133c55e83924734efa78abc03326
Fixes mpv argument syntax (support for old syntax removed in mpv 0.31):
https://anki.tenderapp.com/discussions/ankidesktop/38186-mpvprocesserror-unable-to-start-process
Necessary because we are currently unable to upgrade anki to the
latest version in guix (NPM dependencies currently unpackaged).
