detect externally set CPU affinity

Try to preserve externally set CPU affinity instead of silently
overriding it. If CPU affinity is set externally, e.g. by taskset or
some OpenMP library we don't check for, disable internal CPU affinity
and warn the user. This only works on Linux as it uses the sched.h CPU
set interface which is GNU feature.
