Fix issue 129: Use TEST_TEMP_DIR instead of /tmp for test output files

Replace hardcoded /tmp/drharness_output.txt with $TEST_TEMP_DIR/drharness_output.txt
in all test files. Tests should only write to subfiles/directories of the working
directory (which is already a temp directory created by run_test.sh).
