    oeqa: allow customizing image used by runqemu()
    
    runqemu() takes all parameters for the virtual machine from the
    variables of the given recipe. By allowing the caller to provide a
    hash with variables that get applied locally, the caller gets more
    control.
    
    Here's the intended usage:
    
       <prepare internal-image in self.resultdir>
       overrides = {
            'DEPLOY_DIR_IMAGE': self.resultdir,
            'IMAGE_LINK_NAME': 'internal-image-%s' % self.image_arch,
       }
       with runqemu('refkit-installer-image', ssh=False,
                     overrides=overrides) as qemu:
           ....
    
    This can be used to replace the image completely with something else
    or to copy it before allowing runqemu() to write into it.
