security/ssl-admin: Use the right tarball

The developer has indicated the correcdt tarball supplied in the assets,
not the tagged Github tarball. The Github tarball will provide the wrong
VERSION in the app.

Not mentioned in my previous commit: this release adds a new feature:

C) Generate new Certificate Revokation List (CRL)

While here:

• run portfmt
• remove dependency on archivers/zip by patching to use bsdtar from base (credit to diizzy@ for patch and help with this commit)

Approved by: maintainer (via Github discussions)
