chore(overlays/tvl): Remove stale overlays r/4685

As the comments explain:

> Workaround for srcOnly with separateDebugInfo until
> https://github.com/NixOS/nixpkgs/pull/179170 is merged.

> upgrade home-manager until the service-generation fix has landed upstream
> https://github.com/nix-community/home-manager/issues/2846

> Outdated test-data, see https://github.com/pganssle/zoneinfo/pull/115
> Can be dropped when https://github.com/NixOS/nixpkgs/pull/170450 lands.

All of the linked issues appear merged (or closed with a link to a merge PR),
so -- barring any failing Buildkite builds -- these may be safe to remove.
