Oops, just checked the USB target again after fixing the host machine and found that it had nothing in its EFI partition, so It would not boot either. I thought that specifying the explicit paritition /dev/sdc1 (vs the device /dev/sdc) would work for "removable media" bootlaoder locations on an EFI partitions, but that did not work in this case. The EFI updates went to the hard disk's EFI partition as well, as evidenced by their different size from the 13.04 versions of the signed grubx64 and shim.
