Log Message:
courier-maildirmake has been renamed to courier-maildir.  Handle new
dependency and bump PKGREVISION as a result.

XXX This package should really be changed to build from the latest
XXX courier distribution, much like courier-auth.  This package in its
XXX current form hasn't been updated in years, while the core courier
XXX package notes bug fixes and feature additions to the maildrop code
XXX during that time.
