Don't clean when running e2e tests

[smith]

I don't think this is necessary, and since it's run before bootstrap, the Bazel tools aren't installed so it fails silently.

Example: https://apm-ci.elastic.co/blue/organizations/jenkins/apm-ui%2Fapm-ui-e2e-tests-mbp%2FPR-89647/detail/PR-89647/21/pipeline/124/

Should fix APM E2E failures.
