[PATCH v8 3/5] http: always warn if libcurl version is too old

[Brandon Williams <bmwill@google.com>]

Now that there are default "known-good" and "known-bad" protocols which
are allowed/disallowed by 'is_transport_allowed' we should always warn
the user that older versions of libcurl can't respect the allowed
protocols for redirects.
