tremplin: Drop io_uring from syscalls denied

ChromeOS security has asked for io_uring to be disabled completely in
Crostini. The previous seccomp-based disablement (crrev.com/c/4653823)
was deemed to not be secure.

As io_uring is now disabled in the kernel config (crrev.com/c/4712768),
the seccomp filter is no longer necessary.
