mandos: Avoid closing configured server network socket

If we are passed a pre-created created network socket as a file
descriptor, we must avoid later closing it (when stdin, stdout and
stderr are dup2()ed over with /dev/null) by making sure that the
network file descriptor is not 0, 1, or 2, by creating a new file
descriptor if necessary.

However, when we create a new file descriptor we must check that the
new file descriptor is not 0, 1, or 2 either, and try again until we
get a suitable file descriptor.
