Bug#929197: biber: FTBFS when separate libunicode-collate-perl package is installed

[Niko Tyni <ntyni@debian.org>]

Source: biber
Version: 2.12-2
Severity: important
Tags: fixed-upstream
User: debian-perl@lists.debian.org
Usertags: perl-5.30-transition

This package fails to build with newer versions of Unicode::Collate,
including the separately packaged libunicode-collate-perl package
currently in sid/buster (1.27-1). It builds fine when the separate
packaged version is not installed and Unicode::Collate 1.25 from the
perl core packages (libperl5.28 / perl-modules-5.28) is used.

The test data seems to have since been updated upstream, see commit

  https://github.com/plk/biber/commit/6b61b4c13778cf638f82569ab9e413f09f111ba5

If both Unicode::Collate versions can't be supported at the same
time, I suppose this calls for either a build conflict on the newer
libunicode-collate-perl versions, or updating the tests and bumping the
build dependency to pull in the separate libunicode-collate-perl package.

I assume that this is not considered release critical for buster but
I'm not quite sure.

As the upcoming Perl 5.30 also bundles Unicode::Collate 1.27, this is
a blocker for that transition (which will obviously not happen before
the buster release.)
