core/init: make boot message configurable

Browse Source 
It can be desirable to not have the boot message printed each time
(e.g. logs are transferred over a wireless link on battery) while
still retaining the ability to receive INFO level logs.

This adds the option to disable the boot-up message (and also to customize
it if that is desireable).
