BUG/MINOR: http: always disable compression on HTTP/1.0

Compression is normally disabled on HTTP/1.0 since it does not
support chunked encoded responses. But the test was incomplete, and
Bertrand Jacquin reported a case where if the server responded using
1.1 to an 1.0 request, then haproxy still used to compress (and of
course the client could not understand the response).

No backport is needed, this is 1.5-specific.
