Set GUS patch path variable using D_SetVariable.

commit 42faefce1fd03 added code to set the GUS patch path
automatically when the BFG Edition is installed, but this caused
problems because gusconf.c is not included as part of the build for
the setup tool. Use D_SetVariable() instead which accomplishes the
same thing without a hard dependency.
