rt-tests: cyclictest: Correct short option 's'

The short option 's' was originally intended to be the short form of
--system

Commit b35bc97cfd05bd27324b9c373ff8c5e0bcb07f7f
which added the new option --secaligned broke this, by accidently
inserting the new option between the short form and long form.
