Added "core" services that are run from scripts on stage 1.

- /etc/runit/functions: contains common functions to be used in core-services.
- /etc/runit/core-services: directory containing one-time tasks run in stage 1.
- Added LXC container detection to disable some core services.

This accidentally also fixes the issue of unicode not working in the active
TTY from stage 1.
