The "make integration" target assumes that skopeo will be available on
PATH, but this wasn't documented. Install it during bootstrap when other
utilities are installed. (See ./test/integration/utils_test.go:50).
Include a sample skopeo policy.json, otherwise skopeo will look for a
missing policy doc a /etc/containers/policy.json and exit with an error.
The sample policy document matches the one included by default with
"brew install skopeo".
