Remove graphics/Mesa

This metapackage isn't particularly useful for modern applications and is
potentially misleading.

Not everything needs glu for OpenGL support, and glut has increasingly
fell out of favour, to the extent of being dropped from Mesa. It's
mostly been replaced by e.g. SDL.

Hopefully I've narrowed down everything pulling in the metapackage
and switched everything to using only the individual libraries it needs.
