This reverts commit d17c53b3.

Reason for revert: This makes the GPU process crash on startup on Krane (and probably many other ChromeOS devices).

Original change's description:
> Call PreSandboxStartup after GL initialization in GpuInit
> 
> Fixes "vaInitialize failed: unknown libva error"
> on Wayland with LIBVA_DRIVER_NAME=i965
> 
> VaapiWrapper relies on the GL implementation to decide
> which display to use. If the GL implementation is none,
> then VaapiWrapper is likely to do the wrong guess resulting
> in the above error.
