[jdk17u] RFR: 8274215: Remove globalsignr2ca root from 17.0.2

[Rajan Halade]

"globalsignr2ca [jdk]" was removed with JDK-8225083. This fix got pulled in to 17.0.1 (Oct 2021) release so had to be backed out with JDK-8273150. Since it was not allowed to be backed out from 17.0.1 repo only, it was backed out from 17.0.2 as well.

Now that Oct release is finalized, the fix for JDK-8225083 can be added back to 17.0.2.
