The env-vars doctor check was skipping deacon with a stale comment
"it doesn't use standard env vars". After the AgentEnv refactor,
deacon/manager.go now uses config.AgentEnv() like all other roles.
- Remove the skip condition for deacon in env_check.go
- Update test from TestEnvVarsCheck_DeaconSkipped to test deacon is
actually checked (TestEnvVarsCheck_DeaconCorrect/DeaconMissing)
