[Core] Auto-cleanup after all update_script executions

Implements central solution for automatic cleanup after updates:
- Modified start() function in build.func to call cleanup_lxc after update_script
- Applies to ALL scripts automatically (no individual script changes needed)
- Prevents disk space growth from accumulated caches (yarn/npm/pnpm/composer/pip/etc)
- Aligns update behavior with install behavior (which already calls cleanup_lxc)

This fixes issue #10117 (Jotty disk space growth) and prevents similar issues
in all other scripts that use package managers.

Benefits:
- Single point of maintenance
- Consistent behavior across all update scripts
- Reduces disk usage after every update
- No need to manually add cleanup_lxc to 100+ update_script functions

Impact: All LXC update operations will now automatically clean caches after
successful completion, just like installations do.
