4249098 - SUNWsspue post-install gets permissions wrong on dtwmrc

SUNWsspue post-install script overwrites the dtwmrc file, causing it to be owned by root:other instead of ssp:staff.

Workaround: If you do not change this file, no action is required. However, if you do change the dtwmrc file, you must log in to the SSP as superuser and change the owner and group of the dtwmrc file to ssp:staff, unless you edit this file while you are logged in as superuser.
