fix(src/utils): add warning for unknowndistribution when rebuilding initramfs

Log a warning when the initramfs rebuild is skipped because the distribution is unknown, ensuring the user is informed.

New Features
- None

Enhancements
- Added explicit warning for unknown distributions to prevent silent skips
- Improved logging clarity in rebuild_initramfs

Bug Fixes
- Fixed missing warning path that could hide build issues on unsupported distros
