Move eventd enabled check from build time to runtime (sonic-net#20248)

## How I did it Remove eventd enabled/slim image check from Dockerfile (build time). As part of Dockerfile expose eventd_enabled and slim image flags to ENV which will be used docker_init/start.sh to check if rsyslog plugin should be moved to rsyslog.d #### How to verify it Manual test/pipeline
