I don't see the point.

...and the syslog-ng-config as well as the syslogd-config scripts
also create /dev if it doesn't exist so that syslog-ng/syslogd can
create a /dev/log socket.

I'm under the impression you're thinking about this too complicated.
The script could be a postinstall script in the Base category, so it's
getting run automatically on install.
Cygwin itself does not depend on the existence of /dev, so there's no
problem with order or so. For the virtual devices which are handled by
Cygwin you don't need to call mknod. Just create empty files, like
this:
$ touch `cygpath -am /dev`/null
$ ls -l /dev/null
crw-rw-rw- 1 corinna root 1, 3 Dec 1 2006 /dev/null
As you can see, Cygwin does never evaluate a DOS path as virtual device,
while it always evaluates the POSIX path into the virtual device. Voila.
