Open a dserver console socket when opening "/dev/console"
This allows log messages that programs want to write to "/dev/console"
to be written to darlingserver's log stream instead. The alternative is
to just drop those messages, because "/dev/console" a privileged device
(plus, we don't want to be writing to Linux kernel's console anyways).
