kernelscripts: Add support for modules_prepare for modules
Add support for modules_prepare for preparing kernel for compiling
external modules in parallel. This helps in saving complete android
build time of 10-15 minutes approximately as external modules are
compiled early on without waiting for the kernel image to compile first.
