x86/fpu: Add a pkru argument to copy_uabi_from_kernel_to_xstate().
Both KVM (through KVM_SET_XSTATE) and ptrace (through PTRACE_SETREGSET
with NT_X86_XSTATE) ultimately call copy_uabi_from_kernel_to_xstate(),
but the canonical locations for the current PKRU value for KVM guests
and processes in a ptrace stop are different (in the kvm_vcpu_arch and
the thread_state structs respectively).
In preparation for eventually handling PKRU in
copy_uabi_to_xstate, pass in a pointer to the PKRU location.
