Skip checksum benchmarks on systems with slow cpu 
The checksum benchmarking on module load may take a really long time
on embedded systems with a slow cpu. Avoid all benchmarks >= 1MiB on
systems, where EdonR is slower then 300 MiB/s.

This limit is currently hardcoded via the define LIMIT_PERF_MBS.

This is the new benchmark output of a slow Intel Atom:

```
