Add debug logging to game symlink creation

Log each game's prefix path, detected username, and whether the
Documents/My Games directory exists. Also log when scan_and_link_all
skips a game due to missing directories. This will help diagnose
why some games are not getting their Documents folders symlinked
during prefix setup.
