qemu.py: include debug information on launch error
When launching a VM, if an exception happens and the VM is not
initiated, it might be useful to see the qemu command line and
the qemu command output.
This patch creates that message. Notice that self._iolog needs to be
cleaned up in the beginning of the launch() to make sure we will not
expose the qemu log from a previous launch if the current one fails.
