eduke32: Fix resolution info

[kenmays]

Ref: https://github.com/haikuports/haikuports/blob/master/games-fps/eduke32/eduke32-20180224_6694.recipe

"EDuke32 runs at crazy resolutions like 3072x2304..."

NOTE: Game doesn't go as high in resolution as mentioned in the recipe.
Actual: '2560 × 1440' as mentioned in game screen resolution options.
There might be a patch we could implement to go as high as: 3840 x 2160

This was mentioned on the home page of EDuke32 as well.

Although some errors appeared in console, game play was good and no crashes.
