lintian: remove unused non-main dependency libio-prompt-tiny-perl

[Simon Chopin]

The 2.111.0 version of lintian depends on libio-prompt-tiny-perl which is currently in Universe. This blocks the package from migrating until the MIR is completed. However, this dependency is actually unused in the binary package, as the scripts that use it aren't shipped yet. I'm assuming the dependency is there on a provisional basis, but it's actually blocking for us.

Attached is a debdiff to fix this. The package builds fine and I was able to run lintian on several .changes files lying around my work directory without any issue.

LGTM!

We could have considered downgrading to Suggests instead of fully removing the dependency. But as those scripts in private/ aren't shipped in the binary package at all, it doesn't really matter, as somebody using those would be using the source pkg or git tree directly anyway.
