[zsh] Update prezto and clean up paths

Remove manpath and infopath, because the corresponding tools search
dynamically for files if the variables are unset.

Remove system directories and /etc/paths.d/ from path, since upstream
has removed the path_helper workaround.  Let path_helper now handle
these directories.
