bug: incorrect fields in syslog input plugin parameters

[lukasboettcher]

Describe the issue

The fields Mode, Listen and BufferMaxSize are not set correctly by the operator.

To Reproduce

create a syslog input:

apiVersion: fluentbit.fluent.io/v1alpha2
kind: ClusterInput
metadata:
  name: syslog
  labels:
    fluentbit.fluent.io/enabled: "true"
    fluentbit.fluent.io/component: logging
spec:
  syslog:
    mode: tcp
    port: 6659

check the generated config:

kubectl get secrets fluent-bit-config -o jsonpath='{.data.fluent-bit\.conf}' | base64 -d

Expected behavior

The fields Mode, Listen and BufferMaxSize should be present in the config.
