subrepo: adapt to git's recent renames-by-default

Git turned on renames by default in commit 5404c11 (diff: activate
diff.renames by default, 2016-02-25). The change is destined for
release in git 2.8.0. The change breaks test-subrepo-git, which test
specifically that a moved file is reported as a removal and an
addition. Fix by passing --no-renames (available in git since mid
2006) to the diff commands that don't use --quiet (should make no
difference for those).
