ntdll: Fix NtContinue from within exception context on ARM64.

Browse source 
When handling an exception, NtContinue can be called from within the signal
handler, in which case the raise(SIGUSR2) call ends up getting eaten and
integer register context never ends up getting restored. Switch to the
method used on X86 to avoid these issues.
