task_euid() is a very weird operation. You can see how weird it is by grepping for task_euid() - binder is its only user. task_euid() obtains the objective effective UID - it looks at the credentials of the task for purposes of acting on it as an object, but then accesses the effective UID (which the credentials.7 man page describes as "[...] used by the kernel to determine the permissions that the process will have when accessing shared resources [...]"). Since usage in Binder has now been removed, get rid of the resulting dead code. Changes to the zh_CN translation was carried out with the help of Gemini and Google Translate, and since adjusted as per Alex Shi's feedback.
