    yocto-compat-layer.py: add test_world
    
    "test_signatures" ignores wold build breakage for the sake of
    reporting differences also when a world build is broken. Therefore we
    need a dedicated test that a world build at least theoretically can
    proceed without obvious parse time problems (dependencies, parse
    errors, dangling .bbappends, etc.).
    
    This is similar to the BSP test_machine_world. The difference is
    that test_world doesn't change the MACHINE.
