what-utils missing dependency

[James Cameron]

in what-utils-1.3-0ubuntu1 /usr/bin/what-repo uses col2, so it doesn't work.

on xenial, col2 is provided by package byobu.

on trusty, col2 is available in package bikeshed.

however, it would be simpler if col2 were replaced by an equivalant awk.

e.g.
