fdo#45446: officecfg: turn off SaveBackwardCompatibleODF
As detailed in the bug, this option is the reason why LO writes several
elements and attributes that are not valid in ODF; the corresponding
bugs in the import filters are all fixed in OOo 2.4 or earlier,
so there is no reason to risk interoperability problems with other ODF
impolementations for this any more.
