    periodic: Use a deterministic $PATH for periodic.
    
    Various tools can have alternate versions elsewhere, eg: the GNU
    mailutils port (a dependency of emacs*) brings /usr/local/bin/mail.
    Match the preset PATH in /etc/crontab for deterministic path searches
    even when run manually with a different environment.
