* [build-tools] Check all certificates in provisioning profile during verification

Apple provisioning profiles can contain multiple developer certificates
(e.g., when a team has multiple developers). The previous code only
checked DeveloperCertificates[0], causing false "profile and
distribution certificate don't match" errors when the signing
certificate was at a different index.
