tracing/fastboot: change the printing of boot tracer according to bootgraph.pl

Browse source 
Change the boot tracer printing to make it parsable for
the scripts/bootgraph.pl script.

We have now to output two lines for each initcall, according to the
printk in do_one_initcall() in init/main.c
We need now the call's time and the return's time.
