qemu: Add an option to remove host sdl/gl checking

Add an PACKAGECONFIG in qemu to disable GL acceleration:
* By default configure try best to enable GL acceleration and fail when missing
  host dependency(libSDL and libGL).
* End user can also choose to turn off GL capability, thus remove the host
  dependence in building.

[YOCTO #2407] got fixed.
