cred: delete task_euid()
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.
