RFR: 8344271: Comparison build fails due to difference in doc summary

[Jan Lahoda]

A test ensuring the JDK build is reproducible is failing due to the recent https://github.com/openjdk/jdk/commit/81342acdae82262815e04e1ade7deb2d0f24094a . The reason is the unordered map used when filtering `java.base` out of the list of dependencies.

This patch is resolving that, by moving the filtering to `addIndirectPackages`.
