aarch64: syscalls: clone: fix arg order
...
The clone syscal on aarch64 is the following:
```
SYS_clone, flags, stack, ptid, tls, ctid
x8, x0, x1, x2, x3, x4
```
which is a different order than listed on the man page. Fix the ordering
in the aarch64 syscall dispatch code.

libkernel: CpuOps: add 'static trait bound
...
The CpuOps trait should never hold a reference to any other object. In
fact, it should be a singleton object which is constructed at kernel
boot and live for the entire lifetime of the system. Therefore, it's
safe to add the `'static` trait bound.
