Hi Guix,

This patch updates Zig to version 0.13.0. This is my first
contribution to Guix, and here are a few things to note:

- Just like version 0.10, this version is defined as a variant of
  another version (in this case, 0.10). I made this choice since there
  are some packages that depends on zig, specifying the exact version
  of zig they want. Ideally, we should update those packages to use
  the latest version of Zig, and simplify the zig recipe by removing
  those previous versions.
- The Zig tests are currently disabled. I could not get them to
  work. They depend on being able to link with -lrt, but I could not
  find how to provide the dependency to the tests.

Cheers !
