ipfilter userland: Fix branch mismerge

The work to ANSIfy and adjust returns to style(9) resulted in a mismerge
of a stash when ipfilter was moved from contrib to sbin. An older file
replaced WIP at the time, resulting in a regression.

The majority of this work was done in 2018 saved as git stashes within
a git-svn tree and migrated to the git tree. The regression occurred
when the various stashes were sequentially merged to create individual
commits, following the ipfilter move to netpfil and sbin.
