make-xwidget api change patch

[joakim]

Eli noticed a problem in the make-xwidget function a while back.
The problem is that the function takes 2 arguments that are never used.

The type for the webkit widget also has a redundant -osr suffix.

The patch below attempts to fix these issues.

The changes are uncontroversial, but since it is late in the cycle I ask
for a review.
