Remove unused import from tests/unit/net/data_loader.rs

I noticed the following output at https://travis-ci.org/servo/servo/jobs/104733377#L1146:

<pre>
/home/travis/build/servo/servo/tests/unit/net/data_loader.rs:23:9: 23:33 warning: unused import, #[warn(unused_imports)] on by default
/home/travis/build/servo/servo/tests/unit/net/data_loader.rs:23     use std::sync::mpsc::channel;`
</pre>

Manual inspection also tells me that this import is not used. It seems to have become obsolete by https://github.com/servo/servo/commit/2aa51742460a351abfb746aec4352dd6d27a3c52#diff-46fd738c30b50dc2950348f1563f99b9R7.
