tcely 12c1369b8a main/bind: add previous ISC signing key
Without this TOFU unknown entry, a release signed with the older key
prompts for a trust decision. Avoiding the prompt is desirable.

Also, format GPG details so they are easier to check manually.

Used:
$ gpg --verify bind-*.asc bind-*.tar.gz
$ awk \
    '/gpgfingerprints=/,/(^|[^=])["'\'']$/ {print;}' \
