Masayuki Ishikawa f0bf2143f6 sched: pthread: Fix pthread_join() for SMP 
Summary:
- I noticed 'pthread_rwlock test' in ostest sometimes stops
- This issue happened with spresense:wifi_smp (NCPUS=4) and sim:smp
- Finally, I found an issue in pthread_join()
- In pthread_join(), sched_lock() is used to avoid pre-emption
- However, this is not enough for SMP
- Because another CPU would continue the pthread and exit sequences
- So we need to protect it with a critical section

Impact:
- Affect SMP only

Testing:
- Tested with ostest with the following configurations
- spresnese:smp
- spresense:wifi_smp (NCPUS=2, NCPUS=4)
- sabre-6quad:smp (QEMU)
- esp32-core:smp (QEMU)
- maix-bit:smp (QEMU)
- sim:smp
- lc823450-xgevk:rndis
