Access-Control-Request-Headers value should be lowercase

Source/WebCore:

Access-Control-Request-Headers is used when issuing a preflight request to let the server know
the HTTP headers that will be used when the actual request is made.
As per the W3C specification, Access-Control-Request-Headers value should be set in lowercase.
