lt-qcom-linux-integration: Add init script as part of build process

We have the ramdisk init script into the meta-qcom layer that dosen't
make sense so add the init ramdisk script overlay.

Previously we have an overlay for init rootfs script (functional
testing) so rename it to difference between ramdisk and rootfs
init scripts.
