legal: CA bundle and Intel Bluetooth firmware notices

- THIRD-PARTY-NOTICES.txt gains sections for the Mozilla CA certificate
  bundle (0:/os/certs/ca-certificates.crt; Mozilla CA Certificate
  Program root store as packaged by Debian/Ubuntu ca-certificates,
  MPL-2.0) and the Intel Bluetooth firmware blobs
  (0:/os/firmware/intel/ibt-1040-0041.*, from linux-firmware, Intel
  redistributable firmware license).
- MPL-2.0 full text and Intel's firmware license (with its required
  copyright notice and disclaimer) ship at 0:/os/licenses/.
- Both added to the license's third-party list and man legal.
