Cirrus: Use cached swagger binary

An error was observed in another PR while downloading the swagger
binary.  The error was relating to the upstream egress quota.  Obviously
our downloading it every time for each CI run isn't helping.  Fix this
by moving the download into the image-build process, and simply re-use
the already present binary here.
