[PATCH 11/11] README, SECURITY.md: link the threat model and security considerations

[Ahmad Fatoum]

From: Ahmad Fatoum <a.fatoum at barebox.org>

SECURITY.md says where to report vulnerabilities, but not what counts as
one. The README says nothing about security.

Link the new threat model from both files. In the README, add a short
Security section that also links the Security Considerations chapter.
