ssh does not like Incuding files owned by nobody, which breaks fetchgit:

$ nix build jungle#bench6 -L
Bad owner or permissions on /etc/ssh/ssh_config.d/50-redhat.conf
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists
<...>

$ nix run nixpkgs#bashInteractive --offline -- -c "ls -l /etc/ssh/ssh_config.d"
total 4
-rw-r--r-- 1 nobody nobody 581 Jul 24  2023 50-redhat.conf

I think we will have to either modify nix-portable to bind ssh_config.d to an empty dir or wrap it in another bwrap.

I have tried to update nix-portable to current nix version and restrict the binds that are done in nix-portable but there are still some rough edges until I can get it to work.
