Fix test to check runtimeTempDir instead of .cmux/tmp subdirectory

The test 'should use tmpfile policy by default' was checking for files in
.cmux/tmp subdirectory, which was the path used in the initial (incorrect)
fix. Now that overflow files are written directly to runtimeTempDir, the
test needs to check the tempDir.path directly.
