    Fix warnings during debuginfo generation
    
    Commit f3b87dde removed a needed 'shift' from mingw-find-debuginfo.sh,
    which made debuginfo generation often complain about directories not
    found.
    
    Add the 'shift' back and at the same time improve argument parsing error
    messages.
