[PATCH v2 18/41] test/py: Raise a ValueError if a command fails

[Simon Glass]

At present an Exception is raised if a command fails. This is a very broad
class and makes it difficult for callers to catch the error without also
catching other things, like programming bugs.

Change it to ValueError to make this easier.
