kernel: copy kernel build dir on Per-Device Initramfs compilation
To speedup compilation of Per-Device Initramfs, copy the kernel build
directory for each rootfs ID.
This permits concurrent execution of kernel build without conflicting
with each other at the expense of additional disk space usage.
To limit disk space usage, the copied kernel directory is deleted after
the Per-Device Initramfs image is generated and saved.
