Bug 16242 [Follow-up] Move staff client JavaScript out of language directory

Correcting to a file I missed: circ/offline.tt. This patch corrects the
path to offlinecirc.js.

To test, go to Circulation -> Built-in offline circulation interface.
There should be no errors in the console warning of missing files. The
"Check out" link should work correctly.
