git-gui: simplify PATH de-duplication
git-gui since 8fe7861c51 ("git-gui: assure PATH has only absolute elements.", 2025-04-11) uses a list to maintain order and a dict to detect duplicated elements without quadratic complexity. But, Tcl's dict explicitly maintains keys in the order first added, thus the list is not needed. Simplify the code.
