This limit is not rigid on some platforms such as Darwin and SunOS.

sizeof(sa_familiy_t) if path is empty. see "Autobind Feature" in
unix(7) for details.

rsock_unixpath_len, because it returns not the length of the path,
but the length of a socket address for the path.

ext/socket/unixsocket.c (unixsock_connect_internal,
rsock_init_unixsock): calculate the correct address length of
an abstract socket. Without this fix, sizeof(struct sockaddr_un)
is specified as the length of an abstract socket for bind(2) or
connect(2), so the address of the socket is filled with extra NUL
characters. See unix(7) for details.
* ext/socket/lib/socket.rb (unix_server_socket): don't access the
file system if the platform is Linux and path starts with NUL,
which means that the socket is an abstract socket.
* test/socket/test_unix.rb: related test.
