Subject: [PATCH] zsh-prezto: make zshrc aware of where zsh-prezto is installed
 (#112448)

Without this, the bundled zshrc runcom is useless as it assumes that
zsh-prezto is installed in $ZDOTDIR:-$HOME/.zprezto, so it can't find
its entrypoint. Crucially, the home-manager zsh-prezto module uses this
runcom so is broken without this also.
