For MAKE_ISO=yes builds, squashfs, kernel, initrd, manifests, and sizes
are now placed directly into config/iso-dir/iso-root/casper/ during the
build rather than creating livecd.* intermediates that get linked as
for-iso.* files and then copied into casper/ by isobuild.
This stops publishing the intermediate livecd.* artifacts so that only
livecd.*.iso and livecd.*.netboot.tar.gz are published for ISO builds.

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.
