http/httpguts: remove recursion in HeaderValuesContainsToken

Previously, httpguts.HeaderValuesContainsToken called a
function which could recurse to the point of a stack
overflow when given a very large header (~10MB).

Credit to Guido Vranken who reported the crash as
part of the Ethereum 2.0 bounty program.

Fixes CVE-2021-31525

Fixes golang/go#45710
