tests: remove unnecessary setup_nspawn_root we don't run nspawn in TEST-02-CRYPTSETUP

tests: don't run tests on incomplete setup

tests: fix ls: cannot access /var/tmp/systemd-test.*/journal/*/*.journal don't lose logs from the test machine too

tests: various fixes * remove journal flushing (systemd-journal-flush.service runs journalctl --flush on boot) * use sh -c and PATH instead of @SYSTEMCTL@ expansion * remove unnecessary semicolons etc

tests: do not use systemctl status --failed since v212 calling systemctl status without arguments will show a overall system state

test: rework run_qemu It tries to find a suitable QEMU binary and will use KVM if present. We can now configure QEMU from outside with 4 variables : - $QEMU_BIN : path to QEMU's binary - $KERNEL_APPEND : arguments appended to kernel cmdline - $KERNEL_BIN : path to a kernel Default /boot/vmlinuz-$KERNEL_VER - $INITRD : path to an initramfs Default /boot/initramfs-${KERNEL_VER}.img - $QEMU_SMP : number of CPU simulated by QEMU. Default 1 (from Alexander Graf's script: http://www.spinics.net/lists/kvm/msg72389.html)

test: fix TEST-02-CRYPTSETUP missing generate_module_dependencies call which prevents dm_mod and dm_crypt modules to be loaded

test: remove duplicated code

TEST-01-BASIC, TEST-02-CRYPTSETUP: fixed strip also output more status about failed jobs

test: make it easier to override kernel version

test: factor out testsuite.target, end.service Tests can use the same testsuite.target. Add end.service to call poweroff instead of doing it from ExecStopPost where it may be skipped on failure of ExecStart.

test: use non-blocking systemctl calls in testsuite.service "systemctl poweroff" called from testsuite.service will cause this unit itself to stop. To avoid deadlock, the call must not be synchronous.

test: split of cryptsetup into its own test
