JDK 9 RFR of JDK-8146718: jdk/internal/jimage tests listed in both tier 1 and tier 2

[joe darcy]

Hello,

The combination of the changes for  JDK-8049367 "Modular Run-Time 
Images" and JDK-8087181 "Move native jimage code to its own library 
(maybe libjimage)" put the tests in the directory

     jdk/internal/jimage

in both tier 1 and tier 2. This is incorrect and unnecessary. Please 
review the patch below to remove the tests from tier 1:

diff -r 44ab242c0bfc test/TEST.groups

As a follow-up, I'll verify there are no other overlaps in the tiers.

Thanks,
