Fix the s6 handling

This changes the default s6 service directory to /var/svc.d, also
it changes the code to work with the individual services instead of
forcing a rescan when a service is started or stopped.

s6: Use s6-svc -Dd to stop services

This allows us to get rid of the sleep call in the stop function. Also,
we set a configurable timeout value for stopping daemons.

 Several other variables affect s6 services. They are documented on the

 issues.

s6 supervisor fixes

Add the ability to force-kill a service if it does not go down
successfully. Also, adjust the default wait time for an s6 service to go
down to 60 seconds.
