Subject: [bug#30007] [PATCH 0/2] gnu: borg: Unbundle libb2.

Guix,

This adds a libb2 (BLAKE2) package and makes borg use that instead of
its bundled copy.

Not sure whether it belongs in crypto.scm or the new digest.scm wherein
I randomly plonked it. Not sure whether it matters.

Kind regards,

T G-R
