rwrap: Explicitly zero out sin_zero to silence gcc warnings.

On some platforms, failure to set the sin_zero structure lead to
warnings such as:

resolv_wrapper.c:969:5: warning: missing initializer for field ‘sin_zero’
		        of ‘struct sockaddr_in’ [-Wmissing-field-initializers]

     };
     ^
