./build release: don't do u-boot-only archives

it's a pointless feature, initially added just to one-up
gnuboot and only intended for canoeboot, to provide u-boot
tarballs with deblobbing. this was done, because the parabola
build system has certain limitations so the idea is to provide
them with tarballs. but why? they can just fix their build system...

delete this bloat from lbmk. we only need to provide full sources,
and rom images.
