Don't run the spec_testsuite tests if the submodule isn't checked out. (#409)

Browse Source 
* Don't run the spec_testsuite tests if the submodule isn't checked out.

This way, if someone checks out the repository without checking out the
submodules, they can still run "cargo test".

Also, fix a warning in the generated test runner code.

* Print a message if the spec_testsuite submodule is not enabled.

* Move the `#[cfg(test)]` to the top-level `mod`.
