global: call observers (and start logging) in global_init

Call observers so that the logging infrastructure gets initailized and we
start logging.  Otherwise, unless a default log setting has been modified,
we won't start logging until we daemonize, and we won't get the nice
version banner in the log file.

Unlike the previous attempt to fix this (a3091774), we do this after all
of the lockdep initialization has completed.
