sd-daemon: Add vsock fallback to SOCK_STREAM

SOCK_SEQPACKET is only supported on recent kernels. Let's add a
fallback to SOCK_STREAM if it is not supported.

To accomodate SOCK_STREAM, we also modify
pid_notify_with_fds_internal() to do sendmsg() in a loop as with
SOCK_STREAM, sendmsg() is not guaranteed to write all data in a single
syscall or fail otherwise.
