The previous commit (7cbd0532) added VERSION normalization to the DOWNLOAD
RUN step but forgot to add it to the EXTRACTION RUN step. Each Dockerfile
RUN is a fresh shell, so the extraction step fails with 'VERSION: unbound
variable' when it tries to use ${VERSION} in the SRC variable.
Fix: add VERSION="${ZERO_GRAVITY_VERSION#v}"; to the extraction RUN step
(line 73) so it defines VERSION before using it.
