[PATCH 4/4] t/helper/test-delta: close fd if fstat() fails after second open()

[Hoyoung Lee <lhywkd22@gmail.com>]

When opening argv[3], if open() succeeds but fstat() fails,
the file descriptor is not closed, resulting in a resource leak.
This patch ensures that the descriptor is closed on failure.
