tests: Work around some ancient printf bugs.

Some very old printf implementations (e.g., on ULTRIX 4.5) do not
support negative precision with %.*s conversions in order to behave
as if the precision was omitted.

It is easy to change the rendertest program to avoid this problem,
so let's change it.
