score: Provide two thread pin/unpin defaults
The uniprocessor schedulers do not support systems with more than more
processors. So they rivially support thread pinning and thus the
SMP_FATAL_SCHEDULER_PIN_OR_UNPIN_NOT_SUPPORTED cannot happen.
Add a second default implementation for SMP schedulers which do not
support thread pinning.
Change license to BSD-2-Clause according to file history and re-licensing
agreement.
Update #3053.
