riscv: Use $MAX_SMP in unittests.cfg
MAX_SMP is set by scripts/runtime.bash to _NPROCESSORS_ONLN. This
ensures we don't oversubscribe VCPUs when running with KVM where
it isn't recommended to do so. Use MAX_SMP in unittests.cfg, like
Arm does. Users may override by setting MAX_SMP themselves, e.g.
$ MAX_SMP=16 ./run_tests.sh
