netstat: increase address buffers to avoid and overflow

We use scanf %64[...] to get local addresses, but then we store the result
into a char[64] buffer.  Since scanf always writes a terminating NUL, we
overflow the buffer by a single byte.  Use a buffer of 128 bytes to match
the style of other funcs in this file.
