[Open Office] fix sc-dp-gridlayout.diff to work with older versions of patch

[Jonathan Smith]

When using vanilla patch-2.5.4, sc-dp-gridlayout.diff will not apply. This issue 
has been fixed in an alpha release (2.5.9), of patch, but said release has 
problems of its own. The issue is that the second hunk to be applied to 
sc/source/filter/excel/xipivot.cxx is applied at a line after the third hunk is 
supposed to be applied. In reality, *both* hunks were simply shifted down, but 
older versions of patch don't understand this and throw an error saying the 
hunks are out of order. To fix this issue: replace '@@ -1333,6 +1339,12 @@' with 
  '@@ -1533,6 +1539,12 @@' in patches/src680/sc-dp-gridlayout.diff.
