Env vars for ZSH were moved from /etc/zshrc to /etc/zshenv in #3608 to address an issue with zshrc getting clobbered by OS updates, but /etc/zshenv doesn't exist by default--so *nothing* would get set up for zsh users unless they already happened to have /etc/zshenv. Creating these files if they don't exist. Also cut separate creation of profile.d/nix.sh, which isn't needed now.
