[PULL 28/28] tests/docker: remove debian-powerpc-user-cross

["Alex Bennée" <alex.bennee@linaro.org>]

Despite our attempts in 4d26c7fef4 to keep this going it still gets in
the way of "make docker-test-build" completing because of course we
can't build a modern QEMU with the image. Let's put the thing out of
its misery and remove it.

People who really care about building on powerpc can still use the
binfmt_misc support to manually build an image (or just run the build
from pre this commit).
