Patch by Ankur Sethi: Use layout-management in the OpenWindow of DiskProbe. 

Works around the issue from ticket #1809.

Thanks a lot! Please note some changes I have made:
* When using layout management, use the contructors that don't take BRects
  and "follow modes". (You forgot that for the BButtons.)
* You reversed the button order.
* I found it more convenient to use a BGridLayoutBuilder. And it seemed odd
  to only add the menu bar layout item, not also the label item.
* Finally, to create a patch, cd into the Haiku root folder and use "svn diff",
  like "svn diff src/apps/diskprobe/ > patch.diff". I had to apply your patch
  manually line by line, I am not very firm with "patch", although I am sure
  there would have been a way to do it... :-)

Nice work!
