Add SAA binary to ISO vendor, rename card to Supermicro - DMI

- Extract saa 1.5.0 (Linux x86_64) into iso/vendor/saa — baked into ISO
  at /usr/local/bin/saa via the existing vendor loop in build.sh
- Add saa to the vendor tool loop in iso/builder/build.sh
- Rename the web UI card from "SAA - DMI" to "Supermicro - DMI"
- Remove the redundant description hint about saa on PATH
