Bug#986634: 7zr ignores umask for output directory

[MichaIng]

Thanks for the link with the contained patch. Bumping this as it still 
would be great to see it merged:

-------
diff FileDir.cpp FileDir_fix.cpp
569c569
< if (mkdir( name, 0700 ) == 0) bret = true;
---
> if (mkdir( name, 0777 & gbl_umask.mask ) == 0) bret = true;
-------

Best regards,

Micha
