Move security-related information to SECURITY.md

To follow current best practices, create a short SECURITY.md file in the
root of the repository that contains information about the project's
security policy and guidelines for reporting potential security issues.
Replace the relevant bits of text in other files with references to the
new SECURITY.md file, so that the relevant information only needs to be
maintained in one place.

Replace all occurrences of the generic [email protected] email
with a dedicated address for reporting BIND 9 security issues,
[email protected].
