PBJ-integration-tests fails if package or java_package matches pbj.java_package

[jsync-swirlds]

Description

As part of platform enabling protobuf definitions for gossip events, the package usage was cleaned up to match protobuf recommendations.
This caused pbj-integration-tests to fail because the test compiles both PBJ and protoc and assumes the packages will not match.

The result is a duplicate class error during compilation.

Steps to reproduce

• Add platform to pbj-integration-tests as detailed in issue number 241.
• Run a gradle build of pbj-integration-tests after setting the protobuf git package to 12473-gossiped-events.

Additional context

Partial log:

pbj-integration-tests/build/generated/source/proto/main/java/com/hedera/hapi/platform/event/EventPayload.java:19: error: duplicate class: com.hedera.hapi.platform.event.EventPayload

What should happen

The build should succeed without errors. One possible solution would be to prefix the packages for pbj with pbj when compiling for the integration test only (would require an option to insert a package prefix for the compiler). Not sure if that's reasonable, but it's one option.
