* [PATCH 2/5] test: make a distinction between successful and skipped test

To: io-uring
Currently when the test is skipped, it just returns zero and the test
will be assumed to have been successful so the only way to know
which tests were actually skipped is to search the output and inspect
the code.
Change the tests to return -1 in the case that the entire test
is skipped. Some of the tests are exercising multiple features some of
which may not be available and hence can be skipped - I am not
changing those for now. The rule for the test to be marked as skipped
is that nothing meaningful was actually tested with regards to liburing.
One exception are tests that don't run anything if test file is
provided. I am not sure if it's usefull to mark them as skipped so I am
leaving the original behavior for now.
