bootloader: add DEBUG make flag
make DEBUG=1 tells uefi-build.sh to build the DEBUG target, which adds
lots of diagnostic messages that can be useful for people debugging
firmware or early-boot issues (e.g. register dumps in the default
exception handler).
Test: build and flash bootloader images built with and without DEBUG=1
