Add more structure cli to pcid.
This change adds a subcommand daemonize
that does what pcid
previously did by defualt. This for +1/-1 compat so that the
existing config in the redox repo doesn't break with this change.
This backward compatibility will be removed after that repo gets
the updated config.
