Rollup merge of #136908 - mustartt:aix-mutex-destory-einval, r=joboet

[AIX] expect `EINVAL` for `pthread_mutex_destroy`

Calling `pthread_mutex_destory` on a mutex initalized with the static initializer macro `PTHREAD_MUTEX_INITIALIZER` will result in `EINVAL` if the mutex is not lock/unlocked prior to calling `pthread_mutex_destroy`.
