rm: skip sparse paths with missing SKIP_WORKTREE

If a path does not match the sparse-checkout cone but is somehow missing the SKIP_WORKTREE bit, then 'git rm' currently succeeds in removing the file. One reason a user might be in this situation is a merge conflict outside of the sparse-checkout cone. Removing such a file might be problematic for users who are not sure what they are doing. Add a check to path_in_sparse_checkout() when 'git rm' is checking if a path should be considered for deletion. Of course, this check is ignored if the '--sparse' option is specified, allowing users who accept the risks to continue with the removal. This also removes a confusing behavior where a user asks for a directory to be removed, but only the entries that are within the sparse-checkout definition are removed. Now, 'git rm <dir>' will fail without '--sparse' and will succeed in removing all contained paths with '--sparse'.
