I've updated lp:maas-images to produce new images using the linux-signed kernel on AMD64. New images are produced when http://cloud-images.ubuntu.com/daily/ adds new images so it may take a few days for signed kernels to appear in the stream. Unsupported releases are no longer updated so we'll have to manually regenerate them if we want signed kernels.
The stream also contains all bootloaders including the shim. Once a new shim-signed package is released to Xenial the stream will automatically ingest the the update. Let me know if we want to test an updated bootloader, I can produce a new proposed stream.
