Bug#1083106: libyaml-libyaml-perl: should Break lintian (<< 2.119.0)

[Niko Tyni]

Package: libyaml-libyaml-perl
Version: 0.902.0+ds-1

My reading of #1082612 in lintian is that the versioning change
in YAML::XS had runtime effects other than warning (specifically
skipping YAML processing).

If this is the case, libyaml-libyaml-perl should have a Breaks entry for
lintian versions older than 2.119.0 to prevent broken combinations with
partial upgrades.

This would also help the testing migration machinery to figure out
what to let through in which order.
