/**
* If an EKU extension is present in the end-entity certificate, it MUST contain either the
* anyEKU or serverAuth or netscapeSGC or Microsoft SGC EKUs.
*
* @return true if there is no EKU extension or if any of the EKU extensions is one of the valid
* OIDs for web server certificates.
*
* TODO(palmer): This can be removed after the equivalent change is made to the Android default
* TrustManager and that change is shipped to a large majority of Android users.
