[Fizz] correctly track header length (#30327)

The interstital characters in our link header tracking are not
contributing to the remaining capacity calculation so when a lot of
inditidual links are present in the link header it can allow an
overflowing link header to be included. This change corrects the math so
it properly prevents overflow.
