    test/argparse: change initialization to workaround LTO
    
    When compiled with Link Time Optimization, the existing code
    generated an error, because the compiler was unable to intuit
    that there was space in the flexible array.
    
    In function ‘test_argparse_copy’,
        inlined from ‘test_argparse_init_obj’
            at ../app/test/test_argparse.c:108:2,
        inlined from ‘test_argparse_opt_callback_parse_int_of_no_val’
            at ../app/test/test_argparse.c:490:8:
    ../app/test/test_argparse.c:96:17: warning:
    ‘memcpy’ writing 56 bytes into a region of size 0 overflows the destination
            memcpy(&dst->args[i], &src->args[i], sizeof(src->args[i]));
    
    Initializing a structure with flexible array is special case
    and compiler expands the structure to fit.
    But inside the copy function it no longer knew that.
    
    The workaround is to put the copy inside the same function
    and use structure assignment. Also macro should be upper case.
