Fix: embed Java agent JAR at compile time

Root cause

The new OBI version (14950c5) uses //go:embed embedded/obi-java-agent.jar exclusively to load the Java agent at startup. The Beyla test Dockerfile (Dockerfile-with-javaagent) was building the Go binary first (embedding the placeholder bytes), then copying the real JAR to /obi-java-agent.jar in the final image — a path the new OBI runtime no longer reads. This caused the embedded OBI java agent artifact is missing warning at startup, disabling all Java TLS instrumentation.

Files changed

internal/test/beyla_extensions/components/beyla/Dockerfile-with-javaagent (primary fix)

• Moved javaagent-builder stage before the Go builder stage (matching OBI's own Dockerfile)
• Added COPY --from=javaagent-builder to overwrite the vendor placeholder JAR at vendor/go.opentelemetry.io/obi/pkg/internal/java/embedded/obi-java-agent.jar before make compile-for-coverage runs — so the binary embeds the real agent at compile time
• Removed the now-dead final-stage COPY ... /obi-java-agent.jar line

Makefile (secondary fix — local dev parity)

• Added JAVA_AGENT_EMBED_DIR := vendor/go.opentelemetry.io/obi/pkg/internal/java/embedded
• Updated java-build and java-docker-build targets to output the JAR to $(JAVA_AGENT_EMBED_DIR) instead of bin/, matching OBI's own Makefile convention

Expected CI outcome

• shard-9 TestSuite_JavaKafkaTLS — should produce Kafka TLS spans
• shard-13 TestJavaNestedTraces — should produce outgoing client spans
• run-oats_java_tls_jdk_8, run-oats_java_tls_netty, run-oats_java_tls_sync_async — should find spans in Tempo within timeout
• run-oats_python_outgoing_unresolved — should complete (no longer starved by the 3 Java TLS timeouts)

Upstream note

The OBI Dockerfile-with-javaagent is already correct as of this submodule bump (14950c5). No upstream OBI changes are required.
