Eat some CPU cycles in sceUtilityOskUpdate. Works around timing bug in Ghost Recon Predator.

Browse Source 
The bug is in the game, it uses the wrong vblank wait, but it only works
because the dialog processing takes so much time that it misses the
vblank period anyway.

Fixes #12044, and hopefully won't break anything else.
