sbcl: refactor separate 2.*.nix into single file

Inspired by scala’s 2.x.nix, a bit lower in the same all-packages.nix file, I
have combined all the separate SBCL build declarations into a single 2.x.nix
file which you can call with the version as an argument.

Benefits:

- Less clutter in the filesystem
- Less indirection
- Cleaner overview of available versions

This yields no rebuilds on my machine.
