Update information on CVE-2019-5827/sqlite3

Track upstream commits https://www.sqlite.org/src/info/07ee06fd390bfebe
and https://www.sqlite.org/src/info/0b6ae032c28e7fe3 as fixed for
CVE-2019-5827/sqlite3.

Update fixed version for unstable to 3.27.2-3.

The issue seems to not be possible to directly trigger in sqlite3, so
it's most relevant for chromium and might just be no-dsa for older
suites.
