kernel: make LINUX_DIR configurable for SetInitramfs functions
Rework SetInitramfs functions to take a second arg to define the
location of the .config. This is needed in preparation for PER_ROOTFS
Initramfs support as we will prepare .config in dedicated directory and
use them only later when the image is actually built.
