MdePkg/BasePeCoffLib: Correct the address of RelocBaseEnd
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1426
When calculating the address of RelocBaseEnd,
the RelocBase address is ImageBase + RelocDir->VirtualAddress,
the size of RelocDir is RelocDir->Size.
So the RelocBaseEnd address is:
ImageBase + RelocDir->VirtualAddress + RelocDir->Size - 1
not
ImageBase + RelocDir->VirtualAddress + RelocDir->Size
This patch is to fix this issue when call PeCoffLoaderImageAddress
function to calculate the address of RelocBaseEnd.
