stat: used shared sem for stats lock
Like commit:
21628ec537c7 ("fio_sem, diskutil: introduce fio_shared_sem and use it for diskutil lock")
the stats sem is also potentially shared between processes, and hence
should be allocated and freed as a shared sem.
See the referenced commit, which has more details. Switch the stats sem
to be allocated in such a way that it's propagated properly between
processes.
