Simplify startup and dependencies (#69)

Move file cleanups into a finish script for the service that created the
file (replace 02 / replace 03 commits)

Currently there is a whole dependency forest just to start a couple of
startup scripts in order.
Additionally all the services also have a dependency on all the startup
scripts.
This is unnecessary complex, simplify it:
- Move startup scripts to /etc/s6-overlay/startup.d
- oneshot service named "startup" from underlying image executes
all files in /etc/s6-overlay/startup.d in alphabetical order
- Remove various oneshot scripts from longrun service dependencies
Add "startup" oneshot service to longrun service dependencies

container-version is now being run by said startup script, remove the
double s6wrap prepending of an appropriate log name.
