binder: fix test regression due to sender_euid change
This is a partial revert of commit 29bc22ac5e5b ("binder: use euid from cred instead of using task"). Setting sender_euid using proc->cred caused some Android system test regressions that need further investigation. It is a partial reversion because subsequent patches rely on proc->cred.
