[PATCH 4/8] tests/acceptance/migration.py: cancel test if migration is not supported

[Cleber Rosa]

FIXME: check if there's a way to query migration support before
actually requesting migration.

Some targets/machines contain devices that do not support migration.
Let's acknowledge that and cancel the test as early as possible.
