internal/trace: skip async preempt off tests on low end systems

Browse source 
The OpenBSD armv7 port does not support SMP - on this platform the
trace tests take ~300 seconds to run when async preempt is disabled,
which then times out on the builder. Skip these tests when run in
short mode on a single CPU system.
