[RFC PATCH 1/4] check: add long aliases --iterate and --iterate-while-successful

[Zorro Lang <zlang@kernel.org>]

The -i and -I options iterate the whole test list, but their
single-letter names don't describe what they do.  Add the long aliases
--iterate and --iterate-while-successful so that they can be named
consistently with the --loop family of per-test looping options that
will be added next.
