Uses/makeinfo.mk: Only look for makeinfo from print/texinfo

If systems are updated without running make delete-old, makeinfo
may still be lingering around in /usr/bin. This causes eventual
errors as it can't handle brand new emerging technology from 10
years ago (like CSS).

Instead of permitting makeinfo from base (which was removed in
11.0-RELEASE), depend specifically on makeinfo from print/texinfo.
