sendmail access file and cidrexpand

[Warren Block]

Adding cidrexpand support to the /etc/mail/Makefile would be handy; then 
we could use CIDR notation in /etc/mail/access.  I've edited the 
/etc/mail/Makefile (patch attached), and it seems to work.

The question would be: have I done this in an appropriate way?

Feedback would be appreciated before I submit a send-pr.
