At least we should make sure that the OCSP response is targeted to the
expected certificate. This is important because we pass the file path
to the external script, and if the file is replaced because of
renewal, and nghttpx has not reloaded its configuration, the
certificate nghttpx has loaded and the one included in the file
differ. Verifying the OCSP response detects this, and avoids to send
wrong OCSP response.
