build-redbear: make live (.iso), skip broken overlay repair, fix ICU namespace check

- Changed make all -> make live to produce .iso files
- Skipped verify-overlay-integrity.sh (corrupts recipe symlinks)
- Added ac_cv_namespace_ok=yes to ICU recipe (toolchain libstdc++ stale)
- Fixed  variable reference
- Mini ISO builds successfully via the script
