Subject: init: allow for logging of early userspace

This introduces support for the rd.log and rd.debug kernel command line
options, which log early userspace activity to /run/initramfs/init.log.

Code is largely inspired by Dracut's implementation of early userspace
logging, but without needless complexity and redundancies.
