[pc-snap PATCH] snapcraft.yaml: avoid shell expansion in snapcraft.yaml

[Dimitri John Ledkov]

As per schema, make-paramemters are strings, not interpreted/evaluated
values. Move efi vs vmlinuz choice to build-environment with
declarative advanced grammar to select efi on amd64 only.

 This is failing to build with stable snapcraft so pushing this to get
 the current set of snaps to build. Tested with local snapcraft build.
