s4:torture: add a rpc.samba3.smb-reauth1 test

It does reauth while using an rpc pipe:

* open session
* open lsa pipe
* do lsa getusername
* reauth to anonymous
* do lsa getusername again
* reauth back to original user
* do reauth again

result: lsa getusername is always possible
and always gives the first (authenticated user)
