Add two locks to protect namespaces_list and comm_list. The lock is only needed for multithreaded code, so using mutex wrappers provided by perf tool. Not all the comm_list/namespaces_list accessing are protected, e.g. thread__exec_comm. Because the multithread code for perf top event synthesizing does not touch them. They don't need a lock.
