Stop trying to generate test scripts via autoconf substitution.

Use environment variables instead. This repairs 'make distcheck',
which was running into trouble when it tried to chmod the generated
scripts.

Fixes 17148.

+  o Testing:
+   - Use environment variables rather than autoconf substitutions to send
+     variables from the build system to the test scripts. This change should
+     be easier to maintain, and cause 'make distcheck' to work better than
+     before. Fixes bug 17148.
