tests: avoid spurious failure when 'install-info' program is unavailable

From a report by Dmitry V. Levin:
<http://lists.gnu.org/archive/html/automake-patches/2012-04/msg00085.html>

* t/install-info-dir.sh : When 'install-info' is unavailable, create a
dummy '${infodir}/dir' file by hand when that file is required by later
checks.
