x11/cde: Make cde-25 default

Upstream commit 9af0993de added font aliases, specifically gb2312.1980,
which may be incompatible with some legacy Xm and Xaw apps however there
is a circumvention recommended by the cdesktopenv-code upstream. That is
to add -xrm '*international: true' to the affected app's arguments. A more
elegant approach is to create a ~/.Xdefaults file containing the following
example:

XPostit.*international: false
*international: true
