make check: accommodate stricter POSIX-conforming shells

Without this, test-related variable settings were not exported to
the shell_or_perl_ function when using dash or Solaris 11's /bin/sh.
* tests/check.mk (TESTS_ENVIRONMENT): Use an explicit "export",
so as not to rely on non-POSIX behavior of some /bin/sh (e.g.,
bash-based ones).
