I noticed these weren't actually running on my Fedora host. This turns out to be because cataonit is not in the path on Fedora (it's in /usr/libexec). The podman tests also downloaded and build podman in the test proper, which requires external network access. That's awkward in some cases, and in particular precludes running the tests in an isolated network environment. Move the download and build of podman to the "make assets" stage instead.

New subject: [PATCH 1/3] test: Make sure to update mbuto repository

We download and use mbuto to build trivial boot images for our VM tests. However, if mbuto is already cloned, we won't update it to the current version. Add some make logic to ensure that we do this.

New subject: [PATCH 2/3] test: Build and download podman as a test asset

The pasta_podman/bats test scrpt downloads and builds podman, then runs its pasta specific tests. Downloading from within a test case has some drawbacks: * It can be very tedious if you have poor connectivity to the server * It makes a test that's ostensibly for pasta itself dependent on the state of the github server * It precludes runnning the tests in an isolated network environment The same concerns largely apply to building podman too, because it's pretty common for Go builds to download dependencies themselves. Therefore move the download and build of podman from the test itself, to the Makefile where we prepare other test assets. To avoid cryptic failures if something went wrong with the build, make running the test dependent on having the built podman binary.

The pasta_podman/bats test scrpt downloads and builds podman, then runs its pasta specific tests. Downloading from within a test case has some drawbacks: * It can be very tedious if you have poor connectivity to the server * It makes a test that's ostensibly for pasta itself dependent on the state of the github server * It precludes runnning the tests in an isolated network environment

The same concerns largely apply to building podman too, because it's pretty common for Go builds to download dependencies themselves. Therefore move the download and build of podman from the test itself, to the Makefile where we prepare other test assets. FYI, we use vendoring in podman and most of our other repos. So running something like `make podman` should never download anything. The only target that downloads the deps is `make vendor` which is not needed unless you update the dependencies. Anyhow it doesn't change the fact

To avoid cryptic failures if something went wrong with the build, make running the test dependent on having the built podman binary.

New subject: [PATCH 3/3] test: catatonit may not be in $PATH

The pasta_podman/bats test script looks for 'catatonit' amongst other tools to be avaiiliable on the host. However, while the podman tests do require catatonit, it doesn't necessarily need to be in the regular path. For example Fedora and RHEL place catatonit in /usr/libexec and podman finds it there fine. Therefore, remove it as an htools dependency.
