GLES: Enable the clip planes the vertex shader actually writes

Browse Source 
The vertex shader puts min/max Z in clip distances 0 and 1 and the near plane
in 2, but the program flags still followed an older layout and never enabled
plane 2. Geometry crossing the near plane was then only depth clamped, and
smeared across the screen (Hellboy, FIFA Soccer, Hoto no Ken frame dumps).
