Commit "2565ca7f5ec1 (certs: Move load_system_certificate_list to a common function)" made load_certificate_list() a common function in the certs/ directory. Export load_certificate_list() outside certs/ to be used by load_platform_certificate_list() for loading compiled in platform keys onto the .platform keyring at boot time.
