Related: tdf#128611 RTF import: handle vertical flip of line shapes

UI uses SdrEditView::MirrorMarkedObjVertical() to flip a line shape
vertically, handle it similarly at import time as well.

Also note that this flips in-place, while the naive '*= -1' for the
height would have an incorrect vertical position.

(cherry picked from commit f9f421b7beaf117968c0dbfd84a2dad3dc85136a)
