remove a warning building a test

Browse Source 
With my compile switches (which are mostly derived from RedHat spec
file) I'm getting this warning:

stream-test.c: In function 'sock_fd_read':
stream-test.c:66:43: warning: dereferencing type-punned pointer will
break strict-aliasing rules [-Wstrict-aliasing]
             *fd = *((int *) CMSG_DATA(cmsg));
                                           ^

memcpy could decrease performance but as this is a test it's not
an issue.
