unable to add a builder to the builder set

[XSven]

I wanted to add ExtUtils::MakeMaker::CPANfile as a new builder to Module::Starter::BuilderSet. This addition is part of a new Module::Starter::Plugin implementation.

Module::Starter::BuilderSet is an inaccessible dependency of Module::Starter::Simple::create_build() and no I do not want to copy and paste that method to my plugin to override the implementation provided by the Module::Starter::Simple engine plugin.
