support for Alien::Base 0.005 features

This adds support for `Alien::Base` 0.005 features.  This is contingent on this PR for `[Alien]`:

https://github.com/Getty/p5-dist-zilla-plugin-alien/pull/4

The rationale for this is `Alien::ffmpeg` will require `alien_autoconf_with_pic` be set to 0 for Alien::Base 0.005 and later.  I  will be sending a PR there as well shortly.

Thanks!
