libbpf package for zig

This is libbpf, packaged for Zig.

How to use it

First, update your build.zig.zon with:

zig fetch --save https://github.com/tw4452852/libbpf_zig/archive/refs/tags/1.4.3.tar.gz

Next, add this snippet to your build.zig script:

const libbpf_dep = b.dependency("libbpf", .{
    .target = target,
    .optimize = optimize,
});
your_compilation.linkLibrary(libbpf_dep.artifact("bpf"));

This will add libbpf as a static library to your_compilation.
