[wpt] Fix position-sticky-nested-table.html

wpt/css/css-position/sticky/position-sticky-nested-table.html test was
broken.
It failed in FF/Safari, and Chrome with TablesNG.

https://wpt.fyi/results/css/css-position/sticky/position-sticky-nested-table.html

The broken part of the test insterted an absolutely positioned
element as a sibling of every element with sticky position.
The abspos element is then positioned so that its position matches
sticky elements position.
I am not sure what this was testing.

This does not work for tables, because instertion of abspos sibling
to td element creates an anonymous table wrapper.
The anonymous wrapper becomes abspos container.

This CL removes creation of the abspos element. The test now passes
in all browsers.
