[PATCH 2/3] test: add new test_expect_pytest_success

[David Bremner]

As the name suggests, this is something of a cross between
test_python (reading a script from stdin) and test expect success.

It seemed somewhat redundant to allow our usual kind of file
comparison with pytest scripts, although that will make it tougher to
compare output with the CLI.
