[TESTBUG] AutoUpdate.java need to be modified for 7uX on the sponsor disabled ping setting after modified for JDK-8129374

In out AU tests, after installed prior version such as 8u45 with SPONSORS=0, the “SPONSORS=0” is written to single binary file. Then we add the registry key “DisableSponsors=Y” before doing AU. So when AU to 8u60 in our tests, both the single binary file and the registry key have disabled sponsors. After AU, the ping values include “s300|-149”. It seems that the installer only check the single binary file if there is. So this is right for 8u60.
 
But for 7u80, because 7uX versions do not have single binary feature, so only the registry key “DisableSponsors” is set. So the ping values after AU to 7u80 should include “s300|-144”.
The AutoUpdate.java should be modified for 7uX on the sponsor disabled ping setting
