[Chromoting] Re-enable mouse lock for AppRemoting.
[Chromoting] Re-enable mouse lock for AppRemoting.

crrev.com/695583005 refactored the cursor and mouse lock handling
but was missing the call to have the input handler include the mouse
deltas in the mouse event. This cl simply adds those missing calls
to include the deltas which re-enables mouse lock support.
