tests: use more portable fd redirection in TESTS_ENVIRONMENT

* tests/Makefile.am (TESTS_ENVIRONMENT): Redirection with `exec 9>&2'
is not portable to various Korn shells, and to (at least) HP-UX 11
/bin/sh.  Use a more portable idiom.
See <http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/22488> for
lots of discussion.
