docker: Handle exceptions when looking for docker command
When trying to run docker tests on a host without the docker
command, we get the following Python backtrace:
$ make docker-test-quick@centos6 V=1
.../qemu/tests/docker/docker.py build qemu:centos6 .../qemu/tests/docker/dockerfiles/centos6.docker
Traceback (most recent call last):

OSError: [Errno 2] No such file or directory

make: *** [docker-image-centos6] Error 1
Change _guess_docker_command() to handle OSError exceptions
raised by subprocess.call(), so we will keep looking for other
commands and print a better error message.
New output will be:
$ make docker-test-quick@centos6 V=1
.../qemu/tests/docker/docker.py build qemu:centos6 .../qemu/tests/docker/dockerfiles/centos6.docker
