Bug 42439: Remove event attributes from label-edit-batch.tt

This patch removes an "onload" event attribute from the label batch edit
template. An "onload" event attribute on the body tag can be easily
moved to the $(document).ready block.

To test, apply the patch and go to Cataloging -> Label creator -> Label
batches -> New label batch. As soon as the page loads the "Add by
barcodes" textarea should get focus.
