nix: remove propagated-build-inputs when static

Ports d07852b5f33b4ef2bd19d7f542575502898f9f97 from the nix tree.
This reduces the closure of pkgsStatic.nix down to several packages.
The closure size drops down from 430.7 MiB -> 39.4 Mib.
Ideally of course we would have the nix-cli component not be allowed to
reference any store paths at all, since that's the whole point of static
builds (i.e to be self-contained).
