[CRIU] [PATCH 1/4] Restore registers not present in the sigreturn signal frame

> Add new function arch_set_task_regs_nosigrt(). It allows to restore
> architecture-specific registers not present in sigreturn signal frame.
>
> Each architecture can overwrite this function.
>
> The arch_set_task_regs_nosigrt function restores the registers between the
> final sigreturn and PTRACE_DETACH. We do this at this point because
> we are sure that all threads have already been created.
>
> Add arch_set_thread_regs in pre-dump because some registers may have
> been changed by the parasite infection and they are not present in
> sigreturn signal frame.
