[Zucchini] Fix range error for equivalence validation.

CL https://chromium-review.googlesource.com/1028836 adds patch
validation to ensure equivalence blocks for element pairs would not
span outside the regions for respective elements. The check assumes that
equivalences use absolute offsets for entire "old" or "new" archives.
This was mistaken (and missed in review), since equivalences in fact use
"local" offsets relative to the start of each element. As a result,
ensemble patching for Zucchini-apply would mistakenly trigger the check,
leading to patch failure.

This CL fixes the check. This removes the need for RangeIsInRegion()
(now removed), since RangeIsBounded() suffices.
