What this PR does / why we need it:

This PR removes the component label core from within the _helpers.tpl because it is set specific to each component within the corresponding templates - see #626 (comment).

This partly reverts #626.

To reproduce this issue run the following on #626:

git checkout 70efc03efebf52da11199271af161bf7ab0b656c
helm template falco .  --output-dir /dev/shm/70efc03
kubeconform -strict /dev/shm/70efc03/falcosidekick/templates/rbac.yaml

kubeconform will throw the following errors:

/dev/shm/70efc03/falcosidekick/templates/rbac.yaml - ServiceAccount falco-falcosidekick failed validation: error unmarshalling resource: error converting YAML to JSON: yaml: unmarshal errors:
