Magellan issue for sqlite: Add more information

Link to Fedora and Red Hat bugs manually as long as no official CVE has been
assigned.

Link to Fedora patch and related upstream commit which was done before 3.25.3
was released. In 3.26.0 a new option was introduced, SQLITE_DBCONFIG_DEFENSIVE,
that also can prevent attackers from exploiting the issue. However it seems to
be more intrusive than the other fix.
