http: always warn if libcurl version is too old

Always warn if libcurl version is too old because:

1. Even without a protocol whitelist, newer versions of curl have all
   non-standard protocols disabled by default.
2. A future patch will introduce default "known-good" and "known-bad"
   protocols which are allowed/disallowed by 'is_transport_allowed'
   which older version of libcurl can't respect.
