Code review comment for lp:~cyphermox/ubuntu-mono/secure-icons

I thinking was at package build time, rather than package postinst, but lets give it a whirl and see what happens, and need to sanity check what happens at package removal.

It's probably possible to simply down to something like:

  for icon in ubuntu-mono-{dark,light}/{22,24}/nm-signal-{00,25,50,75,100} ; do
      .../scavenge.py -o $(icon)-secure.svg $(icon).svg $(padlock).svg
  done
