Zhe Weng 9ef2a48919 net/local: Support `SO_SNDBUF` option in `getsockopt` 
For datagram unix sockets, the `SO_SNDBUF` value imposes an upper limit on the size of outgoing datagrams.

Note: We don't support to change the buffer size yet, so only add support to getsockopt now.
Refs: https://man7.org/linux/man-pages/man7/unix.7.html
