[PATCH v2 6/9] tests/avocado/boot_xen.py: fetch kernel during test setUp()

[Cleber Rosa <crosa@redhat.com>]

The kernel is a common blob used in all tests.  By moving it to the
setUp() method, the "fetch asset" plugin will recognize the kernel and
attempt to fetch it and cache it before the tests are started.
