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.
The s6-svc syntax changed for wait-up, wait-ready, wait-down, and
wait-finished. This changes the s6 handling script to use the current
valid syntax.
This fixes#65.
In the past, OpenRC was a hybrid of a centralized and file-scope
license/copyright structure.
I followed the instructions from the Software Freedom Law Center [1] to
convert to a Centralized structure where possible, for easier future
maintenance.

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.
