main: initialize the keyboard from within the video module

The keyboard is being read from OGC_PumpEvents, which is part of the
video subsystem. Therefore ensure that it's initialized in that
subsystem, and not in SDL_main.

This fixes a bug where an application not using our SDL main would
access invalid memory areas due to the keyboard not being initialized.
