[XEN PATCH 2/2] automation: Add qemu to debian:stretch container for smoke test

[Anthony PERARD <anthony.perard@citrix.com>]

From: Anthony PERARD <anthony.perard@gmail.com>

We can add qemu into the container so that there's no need to install
it everytime we run a test.

Signed-off-by: Anthony PERARD <anthony.perard@citrix.com>

Also, smoke tests stopped working as of today due to outdated
root certificate, so container needs to be updated anyway.
    fatal: unable to access 'https://xenbits.xen.org/git-http/xtf.git/': server certificate verification failed.

I haven't push the container yet, I've only pushed it as
debian:tmp-stretch for testing it.
