[BUGFIX] Rootline utility must respect pageOverlayFields

The rootline calculation always overlays all fields
from the pages table. This causes trouble in e.g. the
case that you want to reuse media images from the default
language in other languages. In the previous implementation
(pre 6.x) only the overlay fields from the
 $GLOBALS['TYPO3_CONF_VARS']['FE']['pageOverlayFields']
setting were overlaid.
