BUG/MEDIUM: http: "option checkcache" fails with the no-cache header

The checkcache option checks for cacheable responses with a set-cookie
header. Since the response processing code was refactored in 1.3.8
(commit a15645d4), the check was broken because the no-cache value
is only checked as no-cache="set-cookie", and not alone.

Thanks to Hervé Commowick for reporting this stupid bug!

The fix should be backported to 1.4 and 1.3.
