[BUGFIX] v9: Add l10n exclude to own page fields

Till yet page overlaying was done in an extra table but
pages_language_overlay got removed with TYPO3 v9 LTS so we need to
prevent overlaying this fields. For tt_content it is managed in an other
way, so there is no change needed.

Releases: 8.0.0, 7.3.3
Resolves: #266 #246
