Subject: chkrootkit-printn
Modify chkrootkit's printn to use printf if available.
This improves readability of the output (if no -q given) by right-aligning
the "nothing found" results.
.
A previous comment noted that upstream was not interested in this patch as
printf is not portable. However, this patch should work even if printf is
not present.
