Remove zdnet from pathological_mobile_sites

Since zdnet_patholocial is failing on Nexus6 Webview and it has recently
been refreshed, remove it. The rest of the old pages in
pathological_mobile_sites will be removed next week (following protocol
of removing old pages a week after new ones are added).
