Some minor IM fixes

server-tools/instance-manager/Makefile.am:
  Makefile.am cleanup
server-tools/instance-manager/commands.cc:
  cleanup
server-tools/instance-manager/instance_map.cc:
  fix the problem caused thread deadlock (as load ends up in the find()
  call which now also locks an instance map mutex)
server-tools/instance-manager/listener.cc:
  portability fix
server-tools/instance-manager/manager.cc:
  Ignore SIGPIPE
server-tools/instance-manager/mysqlmanager.cc:
  cleanup
