[jdk8u-dev] RFR: 8303770: Remove Baltimore root certificate expiring in May 2025

[Antonio Vieiro]

Backport of [JDK-8303770](https://bugs.openjdk.org/browse/JDK-8303770) from 11.  Mostly clean (certfile location differs from 11).

Test `jdk/test/sun/security/lib/cacerts/VerifyCACerts.java` passes on `RHEL8, x86_64, gcc8.5.0`.
