Hopefully fixes RT#127691 and GH#1.

rt.cpan.org is going away.

Thanks Lintian!

Build-depend on "debhelper-compat (= 13)" to replace debian/compat.

A dependency of Devel::Cover is currently broken with Perl 5.25.

0.09 has been released already.

Fixes test suite failures on DragonFlyBSD which has no more
compatibility link at /usr/bin/perl since recently.

dh-dist-zilla provides such a feature now.
