[U-Boot] [PATCH 1/6] test/py: require .config to exist

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

If .config doesn't exist, the test will currently throw an exception
because the shell prompt value can't be looked up. It's not obvious how
to resolve this. Fix the code to require that the .config file exist in
the build directory rather than ignoring the issue when it's missing.
Make the error message reference the fact that U-Boot doesn't appear to
be built, and mention how to solve that.
