Subject: test: run QEMU with a timeout unless daemonized

test: run QEMU with a timeout unless daemonized

Dracut tests might hang. The Dracut CI sets a timeout to kill those
hanging tests, but downstream might not configure something similar.

Run QEMU with a timeout (unless daemonized) to avoid hanging tests
forever.

The slowest tests executions that I have seen on Debian/Ubuntu:

* 33:44 for test 11 (5 client tests) on Ubuntu resolute on armhf
* 101:58 for test 60 (19 client tests) on Debian unstable on ppc64el
* 19:58 for test 70 (3 client tests) on Ubuntu resolute on arm64
* 22:35 for test 71 (4 client tests) on Ubuntu resolute on arm64
* 52:48 for test 72 (8 client tests) Debian unstable on ppc64el

These slow tests take between 5:22 and 6:45 for each client tests on
average (ignoring the setup cost). So set the timeout to 10 minutes as
default.
