Up till now ptest-runner2 returns number of failed tests with its
exit status code. Such use case is not recommended [1] and may cause
issues when there are more than 256 tests to be executed.

To alleviate this issue the number of total tests with number of failed
ones is printed before exit. To be more specific - failure of a single
test doesn't indicate that the ptest-runner itself encounter any issue
during its execution.

One can test this change with executing:
./ptest-runner -d tests/data fail
