No, I don't think that is going to work. The perl-modules-5.24 package
Provides: libunicode-collate-perl so I'd expect such a conflict to make
the package unbuildable.

What just might work is dropping the versioned
dependencies on libunicode-collate-perl from biber (as per
https://lintian.debian.org/tags/versioned-dependency-satisfied-by-perl.html)
and build (and possibly runtime?) conflicting on libunicode-collate-perl:
>= 1.17~ or something like that.

But that'd be just bandaid IMO and a real fix would either revert the
relevant Unicode::Collate change if it's a bug, or adapt biber to work
with newer Unicode::Collate versions if it's a feature.
