rt-tests: cyclictest.8: Remove invalid tracing options from the manpage
Most tracing options have been removed from cyclictest since the user can now use trace-cmd together with cyclictest to get the same functionality. Update the manpage to reflect this. Reported-by: Tom Rix <trix@redhat.com> Signed-off-by: John Kacur <jkacur@redhat.com>
