amd64: revert all grub changes for xenial
For LP: #1901906, on other releases we ensured that grub-pc is always
installed with shim-signed. However, xenial has different behavior that
does not work the same. This reverts those changes back to what
livecd-rootfs was before any of those changes were made, keeping only
the autoremove packages work.
