Add new steps to the interpolation (bugfix)

[Hook25]

Description

This job tends to fail on machines with little ram and a GPU. The job already interpolates using the memory to get a reasonable threshold. This adds two new steps.

This script must be run as root.
ubuntu@ubuntu:~/checkbox/providers/base/bin$ sudo !!
sudo ./memory_compare.py 
Results:
	/proc/meminfo reports:	7.11GiB
	lshw reports:	8GiB

FAIL: Meminfo reports 954224640 less than lshw, a difference of 11.11%. Only a variance of 10% in reported memory is allowed.

After patch:

ubuntu@ubuntu:~/checkbox/providers/base/bin$ sudo ./memory_compare.py 
Results:
	/proc/meminfo reports:	7.11GiB
	lshw reports:	8GiB
