Cirrus-CI provides KVM in their Linux containers, so we can also run
our VM-based NetBSD and OpenBSD build jobs there.
Since the VM installation might take a while, we only run the "help"
target on the first invocation to avoid timeouts, and then only check
the build during the next run, once the base image has been cached.
For the the build tests, we also only use very 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).

The jobs are marked as "manual" only, since this double-indirect setup
(with the cirrus-run script and VMs in the Cirrus-CI containers) might
fail more often than the other jobs, and since we can trigger a limited
amount of Cirrus-CI jobs at a time anyway (due to the restrictions in
the free tier of Cirrus). Thus these jobs are rather added as convenience
for contributors who would like to run the NetBSD/OpenBSD tests without
the need of downloading and installing the corresponding VM images on
their local machines.

The jobs on Cirrus-CI sometimes get delayed quite a bit, waiting to
be scheduled, so while the build test itself finishes within 60 minutes,
the total run time of the jobs can be longer due to this waiting time.
Thus let's increase the timeout on the gitlab side a little bit, so
that these jobs are not marked as failing just because of the delay.

On the primary QEMU repository we want the CI jobs to run on the staging
branch as a gating CI test.

Cirrus CI has very limited job concurrency, so if there are too many
jobs triggered they'll queue up and hit the GitLab CI job timeout before
they complete on Cirrus.

If we let Cirrus jobs run again on the master branch immediately after
merging from staging, that just increases the chances jobs will get
queued and subsequently timeout.

The same applies for merges to the stable branches.

User forks meanwhile should be allowed to run Cirrus CI jobs freely.

A typo meant the substitution would not work, and the placeholder in the
target file didn't even exist.

The result was that tests were never run on the FreeBSD and macOS jobs,
only a basic build.

While there might have been bigger differnces between the -base and
the -xcode images in the beginning, they almost vanished in the
current builds, e.g. when comparing the output of the "configure"
step after cleaning up the differences due to temporary path names,
I only get:

Since we're not using Xcode itself at all, it seems like it does not
make much sense anymore to waste compute cycles with two images here.
Thus let's delete the -xcode job now.

This adds support for running 4 jobs via Cirrus CI runners:

 * FreeBSD 12
 * FreeBSD 13
 * macOS 11 with default XCode
 * macOS 11 with latest XCode

The gitlab job uses a container published by the libvirt-ci
project (https://gitlab.com/libvirt/libvirt-ci

) that contains
the 'cirrus-run' command. This accepts a short yaml file that
describes a single Cirrus CI job, runs it using the Cirrus CI
REST API, and reports any output to the console.

In this way Cirrus CI is effectively working as an indirect
custom runner for GitLab CI pipelines. The key benefit is that
Cirrus CI job results affect the GitLab CI pipeline result and
so the user only has look at one CI dashboard.
