Matthew Bauer 16879e2f6a mesa: remove darwin-specific derivations
The ‘mesa-darwin’ stuff was very out of date (2012). This moves darwin
to use the newer mesa. Stuff seems to build okay. Needs more testing
on other stuff though (libraries work). No drivers build but that is
how it should work on macOS.
