    Fix declare copyout in libgomp.oacc-c++/declare-pr94120.C
    
    Testing on the host does not make sense for 'declare copyout' for
    a same-scope stack-allocated variable. Once the copyout is done,
    the variable is gone. Hence, test the variable on the device. This
    can be revisit after the OpenACC semantic has been fixed; but with
    that fix, the test PASSes again with devices.
