Use libtestng7-java as jtreg dependency
Changes:
- Use libtestng7-java as jtreg6 dependency as TestNG 7.x is required in runtime. Regenerate control.
In order to do a sync to Ubuntu we need to have identical control file in the package. As we now have testng7 in Debian, we can update the rules and control file.
Testing:
- built in a local chroot.
Notice: to get all the tests passing we will also need to do jtreg6 upload.
