Patch for alac

Barely maintained upstream and has bugs and security issues, it's also quite a
bit slower than ffmpeg.

Encoding a 60 min file on my Intel Pentium G3220 (FreeBSD 13.1, amd64, ffmpeg
4.4.2)

/usr/bin/time -h ffmpeg -i sample.wav -acodec alac sample-ffmpeg.m4a
        44.02s real             43.32s user             0.37s sys

/usr/bin/time -h alacconvert sample.wav sample-alac.m4a
        1m3.49s real            1m2.00s user            0.85s sys
