Description of problem:
ReaR backup does not recover UEFI systems with unattended/automatic recovery. 

How reproducible:
Always

Steps to Reproduce:
1. Configure a sample Rear backup with below additional options in UEFI systems : 
~~~
ISO_RECOVER_MODE="unattended"
ISO_DEFAULT="automatic"
~~~

2. Boot the backup ISO to recover system automatically. 

Actual results:
When boot with Default Label in menu with 5 seconds timeout, systems drops at recovery mode to login and perform `rear recover` manually.

Expected results:
It should boot in default Label and perform rear recover and automated reboot with given 30 seconds timeout. (Same as in BIOS systems)

Additional info:
Rear version is rear-2.6-17.el9.x86_64
