xmloff: ODF export: actually ODF 1.2 does not allow graphic-properties

... in a style with family "paragraph", as detected by a
--with-export-validation build due to the unit test added yesterday.

So use the loext namespace for the style:graphic-properties element,
and also omit it entirely (and rely on the style:paragraph-properties
attributes fo:background-*) if the ODF version is set to 1.2 or 1.1.

Also adapt a previous check that was missing the "drawing-page" style
family, where the style:graphic-properties is allowed (commit
9746dc9ad62e7f3a39961733f2ac204e90289034)

(regression from 7d9bb549d498d6beed2c4050c402d09643febdfa)
