If analyze-migration.py cannot be run or crashes, the error is currently
ignored since the code only checks for nonzero values in case the child
exited properly. For example, if you run the test with a non-existing
Python interpreter, it still succeeds:

 $ PYTHON=wrongpython QTEST_QEMU_BINARY=./qemu-system-x86_64 tests/qtest/migration-test

Let's better fail the test in case the child did not exit properly, too.
