keepalive: pass the correct arguments to HTTPResponse

python2.7's httplib.HTTPResponse takes the arguments in the following order:
    sock, debuglevel, strict, method, buffering

This was previously passing them in as positional and skipped strict, so we set
strict=method.  I'm explicitly setting strict=True now to preserve the previous
behavior that has been there since this file was created.
