criu(8): Update list of action-script hooks

* "post-resume" was introduced with commit:

 2ab59939
 cr-restore: "post-resume" hook introduced

 This hook is called at the very end, when everything is restored and processes
 were resumed.
 Can be used for some actions, which require operation container, like
 restarting of systemd autofs services.

* "post-setup-namespaces" was introduced with commit:

 eec66f3d
 criu [PATCH] post-setup-namespaces

 Introduce post-setup-namespaces action script

 It needed to have possibility to run cutom script after mount
 namespace is configured

* "orphan-pts-master" was introduced with commit:

 6afe523d
 tty: notify about orphan tty-s via rpc

 Now Docker creates a pty pair from a container devpts to use is as console.
 A slave tty is set as a control tty for the init process and bind-mounted
 into /dev/console. The master tty is handled externelly.

 Now CRIU can handle external resources, but here we have internal resources
 which are used externaly.
