opengl: Fix 64-bit build.

A previous patch broke the 64-bit with the following error message:

  device/generic/goldfish/opengl/system/egl/egl.cpp: In function 'EGLBoolean eglGetConfigs(EGLDisplay, void**, EGLint, EGLint*)':
  device/generic/goldfish/opengl/system/egl/egl.cpp:559:33: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
      *configs++ = (EGLConfig)i;

This was due to the fact that the type of |i| went from uintptr_t to int.
This patch fixes the issue by casting i to (EGLConfig)(uintptr_t)i.
