std/fs/test.zig: Add test for renaming a dir onto an empty dir

Also split the Dir.rename on directories test into 3 tests: - General rename of a directory - Rename of a directory onto an existing empty directory - Rename of a directory onto an existing non-empty directory The only new case is the rename onto an existing empty directory, but splitting the tests this way made them much more understandable.
