[PATCH 4/5] worktree: make core.sparseCheckout and core.ignoreStat per-worktree

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

The first one must be per-worktree because info/sparse-checkout
already is. The second one shares the same nature and should also be
per-worktree.

Note, because info/config.worktree uses .gitignore syntax, you can
negate a default pattern and revert it back to per-repo..
