ubuntu-cpc: only install shim-signed, run autoremove
The CPC build hooks for amd64 incorrectly attempt to install shim-signed
in addition to grub-efi-amd64 and grub-pc. These latter two packages
conflict with each other. Instead shim-signed should install whatever
packages are required.

Additionally, this will ensure that autoremove is run after installing
anything in the CPC build hooks. This is done to avoid shipping images
that include packages that are autoremovable. This will clean-up as
packages are installed and detect any breakage at build time.
