Use the correct DPI scaling factor in LibreOfficeKit for iOS, too

Fixes the rendering of spreadsheets in the iOS app. (The cell area was
rendered at half the scale of the row and column headers.)

Actual code change only in desktop/source/lib/init.cxx, but update
related comments elsewhere to mention CoreGraphics, too, and not just
cairo.
