dovecot: ignore CVE-2016-4983 (again)

I removed the CVE_STATUS setting for CVE-2016-4983 when this recipe was
updated to 2.4.1-4 - but that was a mistake, the CVE database considers
(incorrectly) even the latest version as vulnerable.

Revert that mistake by adding back the correct CVE_STATUS to the recipe.
