bug#21806: TeX Live: missing biber executable

I gave it a try, and below is an initial patch.  It misses some of the
dependencies required to run the test suite, but that shouldn’t be too
hard to address; the next thing is to address issues reported by ‘guix
lint biber’.  Would you like to give it a try?

Note that I didn’t use the Sourceforge URL because they were all
redirecting to the latest release (2.23), despite the “1.8” or “1.9” in
the URL.

Thanks,
Ludo’.
