Drop i386 support from all addons

Remove i386 architecture support:
- isponsorblocktv: Already didn't support i386
- zititunneller: Removed i386 from config.yaml, build.yaml, and Dockerfile
- builder.yaml: Removed i386 from CI build matrix

i386 is a legacy 32-bit x86 architecture that is rarely used in modern
Home Assistant installations. Removing it simplifies builds and reduces
maintenance overhead.
