Preserve the exit code of the diff command in binary_safe_diff.sh
Summary: Some versions of Subversion (1.9 in any case, maybe others) will duplicate diff headers, if the diff command run through --diff-cmd returns 0. This lead to T9970, where the addition of a new file with properties only shows the properties themselves in the review, not the content of the new file. Test Plan: This is a trivial change, is a test needed at all?
