build-system: add another Kirigami hack

We want to be able to roll our own banner image, logo, title, and other
information in the GlobalDrawer - but Kirigami adds an ugly margin
around that. This attempts to remove that margin (but for some reason
there is still a margin on the left side).

This requires the patch command to be installed, but because of the
context sensitivity of the changes, I couldn't figure out how to do
this with sed or perl (which we already require).
