[PATCH 2/2] generic/556: Fix rename test

["André Almeida" <andrealmeid@collabora.com>]

Casefold rename test should check if renaming a file to an equivalent
name fails as expect (e.g. renaming from "file.txt" to "FILE.TXT") and
`mv` correctly identifies that those names refers to the same file.
Currently, the test doesn't do what is expected given that it doesn't
have the file to be renamed, and `mv` returns "No such file or
directory". Fix that by creating test files and checking the correct
output.

Fixes: 12b7dddbc265fcb ("generic: Add tests for filename casefolding feature")
