blacklisting port_inode and socket_inode

port_inode and socket_inode have caused a few issues lately and, as of
right now, they both have open issues against them. For the time being,
I'm going to blacklist them. When the tables are production-ready, we
can re-add them back in to the base linux build.
Customizable LaunchDaemon via a command-line flag

This is in response to #411. Allowing you to specify arguments on the
command-line has more edge-cases than I'd prefer, so I think this is a
bit more of a sustainable solution, especially given that you're already
supplying the tool with a path to your config file (now you can just
track one additional file).
