Comment 21 for bug 1548009

Ok, comparing this to other users of /etc/cron.d it does seem to be a common idiom used there. To update the path to exactly the above form. So this is not making things any worse. I am inclined to let this go on that basis given it is already in yakkety.

/etc/cron.d/anacron:PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
/etc/cron.d/certbot:PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
/etc/cron.d/popularity-contest:PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
