add: update --renormalize to skip sparse paths

We added checks for path_in_sparse_checkout() to portions of 'git add'
that add warnings and prevent stagins a modification, but we skipped the
--renormalize mode. Update renormalize_tracked_files() to ignore cache
entries whose path is outside of the sparse-checkout cone (unless
--sparse is provided). Add a test in t3705.
