Fix a rare failure for imgdiff when random data equals gzip header

In a rare case, a random chunk will pass both the gzip header check
and the inflation process; but fail the uncompressed length check in the
footer. This leads to a imgdiff failure. So, we should treat this chunk
as 'normal' instead of 'inflated' while generating the patch.

Bug: 63334984
Test: imgdiff generates patch successfully on previous failing images.
