[Buildroot] [PATCH 4/4] iucode-tool: rewrite init script

[Carlos Santos <casantos@datacom.com.br>]

- Indent with tabs.
- Use a function for start.
- Use a dummy function that reports OK for stop, restart and reload.
- Pass "-q" to iucode_tool to inhipt usual output taht would otherwise
  interfere with the operation status report.
