bootlinux: diy: add callback support to 9P build tasks

Adds DIY callback variables to 9P build process tasks to display
executed commands and output:

- Git configuration: Shows git safe directory setup
- Patch application: Shows git am commands for kernel patches
- B4 patch series: Shows b4 am pipeline for applying patch sets
- Local version: Shows echo commands for kernel version customization
- Kernel config: Shows make oldconfig process and responses
- CPU detection: Shows nproc command for build parallelization

This improves visibility into the 9P kernel build workflow by showing:
- Git operations for patch management
- Build configuration process
- Patch application from mailing lists via b4
- Kernel configuration and build preparation steps
