Subject: [PATCH 48/72] fds: fix fds list restore
When there exist multi processes need to dump, the child process may
have the same fds as parent process. During the restore processing,
criu choose the process which has the min pid value to be the master
process to recover fds. However, choosing the parent process as the
master process is more suitable.
