Add IPC env vars to host profiler

[mackjmr]

What does this PR do?

This PR adds IPC env vars to core agent/ host profiler when full host profiler is enabled. Necessary for configsync.

Same PR in helm: DataDog/helm-charts#2497

Motivation

OTAGENT-896

Additional Notes

Anything else we should know when reviewing?

Minimum Agent Versions

Are there minimum versions of the Datadog Agent and/or Cluster Agent required?

• Agent: vX.Y.Z
• Cluster Agent: vX.Y.Z

Describe your test plan

• Deploy with host profiler enabled and ensure that the IPC env vars are present in both core agent and host profiler.
• Add IPC env vars override manually with non default port and ensure it takes precedence

To test it is necessary to override as so:

    experimental.agent.datadoghq.com/image-override-config: '{"host-profiler":{"name":"datadog/ddot-ebpf-dev:mackjmr-hp-run-optional"}}'

These same variables are used already in otel collector. Can we move them over to internal/controller/datadogagent/common/envvar.go instead ? It's already in your imports for both features
