t1092: add test for untracked files and directories

Add a test verifying that sparse-checkout (with and without sparse index enabled) treat untracked files & directories correctly when changing sparse patterns. Specifically, it ensures that 'git sparse-checkout set' * deletes empty directories outside the sparse cone * does _not_ delete untracked files outside the sparse cone Signed-off-by: Victoria Dye <[email protected]>
