/etc/crontab is similar enough to parse as correct if you run
"crontab /etc/crontab", but not the same format due to the who field.
Add some limited anti-foot-shooting support and refuse to load
/etc/crontab as someone's crontab.  Users wishing shoot their foot in
this manner may copy /etc/crontab elsewhere. :)
