[arch-general] Update Groff version to 1.22.4

[Stephen Gregoratto]

Apologies Eli, I really didn't mean to make a nuisance of myself on the 
list. I only punted the patch here because there was no maintainer 
listed in the PKGBUILD. Since I saw similar patches doing the rounds on 
the other OS mailing lists I'm subscribed to, I thought I'd submit mine 
here. On second thought the ping was a bit too needy.
