ci: clone zen sibling deps and moxcms during build

Replace single ../zensim clone with full ../zen/* tree needed by
Cargo [patch.crates-io] and path deps on the imageflow-3-rebased branch.

Repos cloned into ../zen/: zensim, zenpixels, zencodec, zenjpeg,
zenlayout, zenpipe, zencodecs, zennode, zenresize, zenfilters, linear-srgb
Also clones ../moxcms (lilith/moxcms fork, non-optional dep).

Updates CROSS_CONTAINER_OPTS to mount ../zen and ../moxcms instead of
the old ../zensim path.
