af_unix: Use offsetof() instead of sizeof().
The length of the AF_UNIX socket address contains an offset to the member
sun_path of struct sockaddr_un.
Currently, the preceding member is just sun_family, and its type is
sa_family_t and resolved to short. Therefore, the offset is represented by
sizeof(short). However, it is not clear and fragile to changes in struct
sockaddr_storage or sockaddr_un.
This commit makes it clear and robust by rewriting sizeof() with
offsetof().
