fix munging of eumm_version in template, when it is set

In versions of Dist::Zilla::Plugin::MakeMaker before 5.020, eumm_version is
set by default; Dist::Zilla::Plugin::MakeMaker::Awesome 0.22 adjusted its
template to handle the changed default, which broke our regexp that matched
against it.

fix minimum perl version required - \N was the bar (5.011), not \K (5.010)
Dist-Zilla-Plugin-MakeMaker-Fallback-0.012

          - fix munging of "use ExtUtils::MakeMaker <version>" since
            [MakeMaker::Awesome] version 0.22 changed the template
          - lower minimum version of perl required by removing a use of \N in
            a regular expression
