Defer minio from the buildable set too (issue 060)

minio's runtime copies the `mc` client from minio/mc:latest — a
Docker Hub pull the mesh build environment cannot make (its docker
reaches the mesh registry, not public Hub), the same isolation that
blocks npm deps. apt-based installs (mongodb's mongosh, mosquitto)
build fine because the build has real internet for apt; only npm and
Docker Hub are redirected. Delivering an external binary or image layer
into a mesh build is the same open question as the npm deps — deferred
with them.
