rgbds: 0.4.2 -> 0.5.1

[sbruder]

This also changes the owner of the GitHub repository and the homepage
URL because the repository was moved to a different organisation (the
old GitHub repository now redirects to the new one).

Also, since upstream switched to GNU Bison[1], the comment about byacc
is no longer necessary.

darwin failure is preexisting https://github.com/nix-community/hydra-check

[meithecatte]

Can I reproduce this failure interactively if I don't own a Mac?

[risicle]

I was going by https://hydra.nixos.org/build/148999310

[risicle]

And now sure enough https://hydra.nixos.org/build/149744255

[meithecatte]

Upstream suggests using up-to-date clang for the Mac build, as that's what gets tested. Not sure how I can check whether that fixes the build, as, again, I don't have a Mac to test with.
