Revert "data/CVE/list: Fix CVE-2018-19758 (libsndfile). Add fixed jessie version."

This reverts commit 3d6e64ef.

Reason: The issue was fixed in DLA-1632-1 and corrctly listed there to
build the cross reference. No need to add version tracking in
data/CVE/list but it was correct for readability to remove the no-dsa
tagged entry.
