Add package for ack

Add a package for [ack](http://beyondgrep.com/install/).  Simply install
the fatpacked script.

It uses '#!/usr/bin/env perl' and it very much not choosy about what
perl it needs.  For now just trust that there's one available, perhaps
someday we can/should uncomment the depends_on('perl').

Follows the methodolgy I used in nextflow.  Has the same
uninstall/install problem that nextflow has, there is an issue in
progress for that: https://github.com/LLNL/spack/issues/1308.

Tested on CentOS7.
