Latter one is abandoned project now, because Go 1.17 has lazy module
loading support: https://github.com/inetaf/netstack/issues/4
So there is no need in huge amount of dependencies anymore with gvisor.
Moreover inet.af contains dependencies that are explicitly marked as
unbuildable under Go 1.19, so it anyway needs some altering. According
to gvisor's commit messages, it is tested to work under 32-bit systems.
