ZTS: Use QEMU for tests on Linux and FreeBSD

This commit adds functional tests for these systems: - AlmaLinux 8, AlmaLinux 9, ArchLinux - CentOS Stream 9, Fedora 39, Fedora 40 - Debian 11, Debian 12 - FreeBSD 13, FreeBSD 14, FreeBSD 15 - Ubuntu 20.04, Ubuntu 22.04, Ubuntu 24.04 - enabled by default: - AlmaLinux 8, AlmaLinux 9 - Fedora 39, Fedora 40 - FreeBSD 13, FreeBSD 14, FreeBSD 15 Workflow for each operating system: - install qemu on the github runner - download current cloud image of operating system - start and init that image via cloud-init - install dependencies and poweroff system - start system and build openzfs and then poweroff again - clone build system and start 3 instances of it - the functional testings complete within times < 3h Signed-off-by: Tino Reichardt <[email protected]> Signed-off-by: Tony Hutter <[email protected]>

+Workflow for each operating system:
+- install qemu on the github runner
+- download current cloud image of operating system
+- start and init that image via cloud-init
+- install dependencies and poweroff system
+- start system and build openzfs and then poweroff again
+- clone build system and start 3 instances of it
+- the functional testings complete within times < 3h
