[PATCH v1 21/25] tests/docker: update and flatten debian-hexagon-cross

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

Update to the latest stable Debian. While we are at it flatten into a
single dockerfile as we do not need anything from the base image to
build the toolchain.

Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
