support/testing: add runtime testing for init systems

The "builtin" kernel does not boot a systemd-based system, so we resort to building the same one as currently used by our qemu_arm_vexpress_defconfig. We test the 8 following combinations: - busybox, read-only, without network - busybox, read-only, with network - busybox, read-write, without network - busybox, read-write, with network - basic systemd, read-write, network w/ ifupdown - basic systemd, read-write, network w/ networkd - full systemd, read-write, network w/ networkd - no init system, read-only, without network The tests just verify what the /sbin/init binary is, and that we were able to grab an IP address. More tests can be added later, for example to check each systemd features (journal, tmpfiles...) Signed-off-by: "Yann E.
