[linux-uc20-efi][FOCAL][PATCH 2/2] UBUNTU: [Packaging] automatically detect flavours from build-deps

[Dimitri John Ledkov]

Automatically detected from build-deps which flavours to build
kernel.efi apps for. This means that suffixes of
linux-image-unsigned-$(ABI)-* are used to determine the desired
flavours.

If this parsing becomes insufficient, it might need to be updated to
use python-apt in the future, or encode flavours in
$(debian)/flavors.mk or some such.

This makes it trivial to build derivative kernel.efi apps, by simply
adjusting appropriate control.stub with the desired flavour
build-deps.
