sysutils/paladin: update 1.1.1 -> 2.0.0

• An -f command line flag that allows specifying a config file
• A handle for the SIGINFO signal
• Args to the children are passed as an array (so that it's possible to pass an argument with a space in it)
• Fixes of some major bugs causing paladin to not correctly track the number of running children (so it wouldn't know when to exit), or not wait for children to exit before exiting itself after receiving SIGTERM.
