partial revert tdf#116071 import to XATTR_FILL not RES_BACKGROUND

caused by commit 3539a1efb41a787237e4333ebc715db96ffacb5b
which fixes table-related regression bug report tdf#128608.

I was not able to create a unit test for this from scratch.
In fact, if I use MSWord2003 to roundtrip the file, then LO
opens it without problems.

A real fix (to move LO away from RES_BACKGROUND in tables) should
be subject to lots of testing time, so just reverting for now.
