Convert banner() and printv() to use new screen_init() values

Browse Source 
This patch changes the traditional look of the Finit boot sequence.
Now we stick to the screen width probed by screen_init(), or max
132 chars.

Also, some minor cleanup of the currently unused print_timestamp()
method used by printv() when showing [ OK ] or [FAIL] of services
at boot.
