Fix hit testing on border-radius elements

When an element with border radius has children, and
the element should clip overflow and has it's own paint
layer, we were not detecting that children should be
skipped for hit testing when the point is outside the
inner border clip rect.

This change refactors the code to always check for
border radius when ShouldClipOverflow is true,
regardless of the self painting layer status.

We already had test coverage with the failure hidden
in js-test expectations. A previous change converted
the test to testharness.js and now we can delete the
failing expectations file.
