[PATCH 1/2] BaseTools/PatchCheck.py: Fix misreport for binary changes in patch

[Hao Wu <hao.a.wu@intel.com>]

For a patch file that:
1. Contains a binary change
2. Contains any other changes after the binary change

PatchCheck.py will complains with the following error:
* Patch format error: diff found after end of patch
   Line: literal XXXX

This commit resolves this misreport.
