The fstat call can take a long time to finish when running over
NFS. Add a version of it that runs in the thread pool.
Adapt one of its users, raw_co_get_allocated_file size to use the new
version. That function is called via QMP under the qemu_global_mutex
so it has a large chance of blocking VCPU threads in case it takes too
long to finish.
