kernel: relocate copy of module.lds to module compilation task

There were two copies of this patch floating around, and the merged
variant has the copy in the wrong place.

module.lds is only created during modules_prepare, and that target is
not invoked during our main build of the kernel. We aren't about to
change the kernel build (there's no need), so we move the copy into
the compile_kernelmodules task. After that runs, we have module.lds
availble to copy.

This has been tested against clean kernel + out of tree module
builds, and the dependencies are correct that the file is copied
before the out of tree module build starts.
