Patch to upgrade mail/filtermail to 0.8.6

With OSVERSION: 1300094 portscout reports failure to build

This appears to be caused by a recent update to contrib/flex from 2.5.37 to
2.6.4 where upstream changed yyin and yyout from pointers to references.

I've upgraded filtermail to 0.8.6 and added textproc/flex as a conditional
dependency for ${OSVERSION} < 1300000.

This builds and runs successfully on 13.0-CURRENT and 12.1-RELEASE-p5
