Temporary snprintf-related fix to service-win32/openvpnserv.c

This is intended just as a TEMPORARY solution to get the 2.2-RC released.
The intesion is to get this fixed with a better solution for the final 2.2
release.  This patch has also been discussed here:

http://thread.gmane.org/gmane.network.openvpn.devel/4325/

The only reason for this patch to be accepted in its current shape, is
that it will be fixed before the final 2.2 release.
