This allows netboot tarballs to be PXE booted on QEMU; previously, the tarball was missing bootloader.

* Fix some issues with the netboot tarballs:
- Include the signed shim (oops).
- Make the kernel path on disk and in the bootloader config match (more
oops).
- Make paths more architecture dependent as the code in grubnetXXX.efi to
probe a platform dependent path first doesn't work.
