Add a mapping for CSSMERR_APPLETP_SSL_BAD_EXT_KEY_USE on OS X

On OS X, add an explicit mapping for CSSMERR_APPLETP_SSL_BAD_EXT_KEY_USE
to silence additional log spam when a certificate chain does not match
its key usage policies.

The error is still mapped to CERT_STATUS_INVALID, this just unifies the
handling on OS X with other platforms.
