Mac PM test: Require pre-installed rosetta

Previously, the mac podman-machine tests installed rosetta before
executing any tests.  As a best-practice (and because the Macs in CI are
shared) tests should never permanently modify the system.  As of this
commit, the system setup script used for the CI Macs does the rosetta
installation.  Remove the test setup code that installed rosetta and
add a CI-level confirmation that it's been pre-installed.
