They were initially skipped in this PR #12

@leehinman when I unskip the RPM test it fails with:

exec /entrypoint.sh: exec format error
    pkg_test.go:69: failed while running FPM in docker: running "docker run -e EXEC_UID=1001 -e EXEC_GID=1001 --rm -w /app -v /opt/buildkite-agent/builds/bk-agent-prod-aws-1710955016499697865/elastic/elastic-agent/dev-tools/mage:/app docker.elastic.co/beats-dev/fpm:1.13.1 fpm --force --input-type tar --output-type rpm --name brewbeat --architecture x86_64 --rpm-rpmbuild-define _build_id_links none --rpm-digest sha256 --version 7.0.0 -p build/distributions/brewbeat-7.0.0-SNAPSHOT-x86_64.rpm build/distributions/tmp-rpm-mage-7.0.0-SNAPSHOT-windows-x86_64-7478054086.tar.gz" failed with exit code 1

Since you're working on RPM now, you might want to have a look at this test too.
