[PATCH] cirrus.yml: Add VM-based jobs to test with NetBSD and OpenBSD

[Thomas Huth <thuth@redhat.com>]

Since Cirrus-CI provides KVM in their Linux containers, we can also run
our NetBSD and OpenBSD build jobs there. Since the installation might
take a while, we only run the "help" target on the first invocation,
and check with the major targets afterwards, once the base image has
been cached. For the the build tests, we also only use a limited set of
target CPUs since compiling in these VMs is not very fast (especially
the build on OpenBSD seems to be incredibly slow).
