base/shell/cmd : move failure does not raise nErrorLevel

When performing a move to an open file, you get an error message,  but %errorlevel% is still 0

you can try it out by

• start cmd.exe
• copy cmd.exe test.exe
• move /Y test.exe cmd.exe
  you get errormessage with :  ...\test.exe => ...\cmd.exe [Error]
• echo %errorlevel%  states 0 instead of 1

to fix it:
edit move.c,  changes lines 498 - 501  (from github 2c66af on Oct 3, 2017 )

        if (MoveStatus)

            ConOutResPrintf(STRING_MOVE_ERROR1);

        else

            ConOutResPrintf(STRING_MOVE_ERROR2);

to

        if (MoveStatus)

            ConOutResPrintf(STRING_MOVE_ERROR1);

        else {

            ConOutResPrintf(STRING_MOVE_ERROR2);

             nErrorLevel=1;

        }
