[PULL 18/18] tests/functional: Replace the ppc64 e500 advent calendar test

[Thomas Huth <thuth@redhat.com>]

From: Cédric Le Goater <clg@redhat.com>

Replace the advent calendar test with a buildroot image built with
qemu_ppc64_e5500_defconfig. Unlike the advent calendar image, this
newer buildroot image supports networking, too. Thus boot a ppce500
machine from kernel and disk, test network and poweroff.
Add '-no-shutdown' to the command line to avoid exiting from QEMU
as it seems to bother the functional framework.
