test: match container version to host

Instead of just using the "latest" container everywhere, which will
change every time a new release is made, add a build argument to
specify the version and then match that version to the host in all
the build scripts. This will make it possible to use the tests for
gating, and ensure that we test the plugins on the OS version that
is targeted.
