xmloff: ODF export: fix crash on tdf125455-2.odt

FillBitmapMode is a very funny property that is stored as 2 items
XFillBmpTileItem XATTR_FILLBMP_TILE and
XFillBmpStretchItem XATTR_FILLBMP_STRETCH
and the XPropertySet implementations for it are a bit inconsistent,
e.g. sd uses .GetItem<XFillBmpStretchItem> which searches the parent
and requires both items to be present,
but sw uses GetItemState(XATTR_FILLBMP_STRETCH, false) which does not
check the parent and one item is enough.

Let's just not export the attribute in case the property isn't defined.
