create missing profile files to fix zsh envvars

Browse Source 
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.
