Subject: [PATCH] Apply the correct page margins from the QPageLayout to
 Chromium printing

If one passes a QPageLayout to printToPDF, surely one expects the margin
settings contained in it to actually get applied.

This is a partial backport of the much larger 5.8 commit
af2535018b1553e351198f3d9c21538de1c328a1 (by Michael Bruning), limited
to only the margin fix.
