Subject: [PATCH] MT#63401 jquery upgrade: restore .attr( behaviour

repeatable section selectors fail to recognize the selected ceckbox,
because .attr() is used, but newer jquery would need .prop().

the compat layer is extended to restore .attr() behaviour.

Change-Id: I2dc23cb4dd120080cd6d9aa9d3902ed7285c977b
(cherry picked from commit 9752c6c2903107063a99450cd0a8d19943248729)
