fix: Remove name="basics_imuxsock" parameter from imuxsock type input

- Input of type imuxsock does not support the "name" parameter.
  When name is provided, rsyslog ouputs this error:
  parameter 'name' not known -- typo in config file?
- Indend if expressions for style
- Do not append input_template.j2 when use_imuxsock

See RHEL-35561
