app/rpc: Add cpumask to output of thread_get_stats RPC 



Thread's core affinity had not been visible to users.  This patch
adds thread's core affinity information to the existing
thread_get_stats RPC.  We can create an new RPC to retrieve
thread's core affinity information but using thread_get_stats
RPC will be enough for now.

Besides, the name of SPDK thread 0 is not reactor_0 but app_thread
now.  So fix it together in this patch.
