tests/functional: Add a OS level migration test for pseries

Browse Source 
There's currently no OS level test for ppc64le. Add one such test by
reusing the boot level tests that are already present.

The test boots the source machine, waits for it to reach a mid-boot
message, migrates and checks that the destination has reached the
final boot message (VFS error due to no disk).
