Make s6-linux-init a real init package.

 This means:
 - removing leaky options to s6-linux-init-maker. Default initial_path is
now always /usr/bin:/bin; the uid and gid of the catch-all logger (used
at boot time) can now be given numerically instead of relying on the
(run-time) user db mapping.
 - moving s6-halt, s6-poweroff and s6-reboot over here, from s6-linux-utils
 - clarifying on the documentation a bit.
