    bitbake: lib/bb/command: fix overrides in remote datastores where there is no default
    
    If you have, for example, no value set for a variable VARIABLE and a
    then VARIABLE_pn-something = "value" and then you parse something.bb,
    you expect getVar('VARIABLE') on the resulting datastore to return
    "value", but the code here assumed that if the variable wasn't set
    without overrides then we didn't need to return the overridedata and
    thus we didn't get the overridden value.
    
    In OE this affected the ability to get RECIPE_MAINTAINER for a recipe
    in a script using tinfoil (since this is only set from an inc file with
    _pn- overrides for each recipe, and no default is set).
