Pin nixpkgs

This patch pins nixpkgs to an OLD revision, because in newer nixpkgs,
boost changed and libdjinterop does not find it during build, causing
nix-shell to fail.

This fixes this by pinning, which is not the best idea, but works.

Note that this results in mixxx being build against QT 5.12 rather than
5.15!
