mpv-fourier pkgrel=7 + workflow: printf instead of yes (SIGPIPE makes pipeline fail under pipefail)

Run #70 actually succeeded at the pacman level (log shows ffmpeg
removed and ffmpeg-v4l2-request-fourier installed) but the step
exited non-zero. Cause: bash's set -o pipefail (Gitea Actions
default) sees `yes` get SIGPIPE'd when pacman closes its stdin,
yes exits 141, pipeline reports 141 → step fails.

Replace `yes y | pacman -S ...` with finite-stream printf that
exits 0 cleanly. Three y's cover all expected prompts.
