Cirrus: Fix cirrus cache race on bin/podman

A suspected race on uploading gopath cache is causing the docker-py (and
possibly other) tasks to fail unpredictably with an error from `make`
regarding missing `bin/podman`.  Since this failure is affecting all
development activity, apply a quick/dirty fix to the failing task, by
simply rebuilding the binary.  A more comprehensive/long-term fix will
be worked in a future PR.
