Added support for Zig package manager (build.zig.zon) and switched default Zig
to zig-0.13, please see the two DRAFT commits.  I have also updated and added
some packages as examples.

Since Zig has command line option changes in 0.11 (those are affecting us:
"-Drelease-safe" -> "-Doptimeze=ReleaseSafe", new "-j"), I added a zig-arguments
procedure which returns an alist mapping command line options.

Motiejus raised concern about Zig's bundled abilist file[1][2], which is
generated from sources of various glibc versions.  How should we treat it?
