The virtio_balloon test is currently hanging for unknown reasons
when being run on the shared gitlab CI runners (which don't provide
KVM, thus it's running in TCG mode there). All other functional tests
that use the same asset (the Fedora 31 kernel) have already been
marked to work only with KVM in the past, so those other tests are
skipped on the shared gitlab CI runners. As long as the problem isn't
fully understood and fixed, let's do the same with the virtio_balloon
test to avoid that the CI is failing here.

There are two race conditions in the recently added virtio balloon
test
* The /dev/vda device node is not ready
* The virtio-balloon driver has not issued the first stats refresh
To fix the former, monitor dmesg for a line about 'vda'.
To fix the latter, retry the stats query until seeing fresh data.
Adding 'quiet' to the kernel command line reduces serial output
which otherwise slows boot, making it less likely to hit the former
race too.

Increase the timeout for more headroom.

The zstd command will print incremental decompression progress to stderr
when running. Fortunately it is not on stdout as that would confuse the
TAP parsing, but we should still not have this printed. By switching
from 'check_call' to 'run' with the check=True and capture_output=True
we'll get the desired silence on success, and on failure the raised
exception will automatically include stdout/stderr data for diagnosis
purposes.

If the QEMU binary was built for a 32-bit ELF target we cannot run the
memory address space tests as they all require ability to address more
RAM that can be represented on 32-bit.
We can't use a decorator to skip the tests as we need setUp() to run to
pick the QEMU binary, thus we must call a method at the start of each
test to check and skip it. The functional result is effectively the
same as using a decorator, just less pretty. This code will go away when
32-bit hosts are full dropped from QEMU.
The code allows any non-ELF target since all macOS versions supported
at 64-bit only and we already dropped support for 32-bit Windows.
