Bug#774073: dh-make-perl: Ceating core module, install fails with "trying to overwrite foo which is also in bar"

[Andy Beverley]

Package: dh-make-perl
Version: 0.75-1
Severity: normal
Tags: upstream patch

When creating an updated version of a module that is already in core,
the subsequent install fails (as expected) with a message such as:
"trying to overwrite '/usr/bin/instmodsh', which is also in package
perl 5.14.2-21+deb7u2".

Given that dh-make-perl has to be forced into creating core modules,
I think it's appropriate to instruct dpkg that the package contains
files that replace the core module. This patch does so.

If you think it's more appropriate, I'd be happy to create a further
doc patch and/or another command line option to go with this patch.
