[PATCH] t1091: cone mode list deduplicates and normalizes paths

[Pushkar Singh <pushkarkumarsingh1970@gmail.com>]

Ensure that git sparse-checkout list in cone mode collapses
semantically identical paths (e.g. "folder1", "folder1/",
and "./folder1") into a single canonical entry.

This protects user-visible behavior across different ways
of specifying sparse-checkout patterns.
