[PATCH 1/2] Fail run-all on non-zero exit codes and summarise the results

[Alexander Bantyev]

Previously it was hard to determine whether the tests passed or not.
With this change, run-all exiting with 0 means that no tests failed.

This allows us to set up CI for our bash package in the NixOS distribution:
https://github.com/NixOS/nixpkgs/pull/435033

We hope that it will also be useful for other distributions to make sure
their packaging is correct.
