Including changes to mnexec -c to reduce the number of close() system calls, which may help with performance in containers on Ubuntu 22.04. Note that systemd-udevd also seems to be a cause of performance issues and should probably be disabled while running Mininet. Adding dbeug logging to test_simpleperf because it is failing intermittently. (Note with packet loss it can fail, but this is not how we should be testing it.)
