devel/ocfpcsc: Expand license permissions

The license added to the PR was unnecessarily restrictive and caused
the builders to no longer package the binaries.  I looked at the IBM
licence provided in files and did not see any restriction on packaging
object files.  I alerted the maintainer about this twice, and wg@ told
me to Just Fix It.

mail/milter-manager: Explictly request ports package system

Without this configure argument, the makefile will assume it's building
on pkgsrc when building on DragonFly.  No-Op for FreeBSD.
Add notes about a possible package conflict in TeXLive 2014 upgrade.
