graphics: Remove adapta-gtk-theme

This package is causing a lot of problems in bulk builds. There's no reason
all the SVGs can't be pregenerated, but instead it needs to do a few hours
of parallel conversions with inkscape.

it's now unmaintained upstream so there's little chance of it getting
distributed in a more sensible way in the future, and as maintainer, I
no longer care about this package
