Previuously net-test-server-config was written to /data/shared,
which is then mapped to /test-shared in the test launcher. The problem
was that this approach breaks when test launcher is not used (i.e. with
--single-process-tests flag). Updated runner scripts to copy the file to
/tmp. This approach is more consistent with other platforms and doesn't
require any special logic in the test launcher.
