BUILD: http_fetch: address a few aliasing warnings with older compilers
gcc-4.4 complains about aliasing in smp_fetch_url_port() and
smp_fetch_url_ip() because the local addr variable is casted to sturct
sockaddr_in before being checked. The family should be checked on the
sockaddr_storage and we have a function to retrieve the port.
The compiler still sees some warnings but these ones are OK now.
