Revert of Don't process HSTS/HPKP headers when host is an IP address

Revert of Don't process HSTS/HPKP headers when host is an IP address (patchset #9 id:160001 of https://codereview.chromium.org/1059303002/)

Reason for revert:
This change seems to break WebSockets tests broken on Mac: https://build.chromium.org/p/chromium.mac/builders/Mac10.6%20Tests/builds/758

Tests need to be fixed before it can be re-landed.

Original issue's description:
> Don't process HSTS/HPKP headers when host is an IP address
>
> HSTS/HPKP headers should only be parsed when the host is not an IP
> address. This change requires fixing the HSTS/HPKP tests to use
> localhost test server URLs instead of 127.0.0.1, with a corresponding
> cert.
