socket: add new Symlinks= option for socket units
With Symlinks= we can manage one or more symlinks to AF_UNIX or FIFO nodes in the file system, with the same lifecycle as the socket itself. This has two benefits: first, this allows us to remove /dev/log and /dev/initctl from /dev, thus leaving only symlinks, device nodes and directories in the /dev tree. More importantly however, this allows us to move /dev/log out of /dev, while still making it accessible there, so that PrivateDevices= can provide /dev/log too.
