gnu: Move openmw-openscenegraph to graphics.scm.

Package inheritance across modules may cause unbound variable errors at
expansion time because of cyclic dependencies between the modules.

* gnu/packages/game-development.scm (openmw-openscenegraph): Move from here ...
* gnu/packages/graphics.scm (openmw-openscenegraph): ... to here.  Make the
variable public and "hide" the package.
