[Buildroot] [git commit] iucode-tool: rewrite init script

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=9e323088cb179f6b3d8bcb9ec388eb41c1d018e4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

- Indent with tabs.
- Use a function for start.
- Pass "-q" to iucode_tool to inhibit usual output that would otherwise
  interfere with the operation status report.
