    [RSYM/x64] Make command line compatible with x86 version
    
    x86 version needs input and output file names as arguments, even if is called with
    input file name = output file name.
    x86 version also accepts a -s argument to the root path of ReactOS sources
    
    Make x64 version take the same arguments.
