tdf#89698 DOCX import: inline picture should have no spacing

Commit 3d7e168a (n#783638 DOCX import of
wp:inline's distT/B/L/R attributes, 2012-10-11) was about a picture that
had non-zero spacing in LO, but zero in Word. The hope was that the
problem is just that the value is not imported.

Then commit a88ac708 (fdo#63685
wp:inline's distT/B/L/R is in EMU's, not twips, 2013-04-19) was about a
picture that had so large spacing that the picture become invisible.
Fixing the unit of the spacing value made the picture visible again.

What was missed is that this value is just stored in the doc model, but
layout in Word doesn't use it at all till the anchoring is as-char.
Given that in LO as-char anchoring supports real spacing, just don't
import these values to have the same layout. That's what the WW8 import
does, too.
