cyclictest: add --tracemark option

cyclictest will only write to /sys/kernel/debug/tracing/trace_maker
if it's also setup to do tracing. This conflicts with
running cyclictest under trace-cmd.

The --tracemark option tells cyclictest to write to the
trace_marker file even when it's not doing tracing.

It can be used like this:

 # trace-cmd record [...] cyclictest [...] -bX --tracemark --notrace
