tracing/fastboot: fix initcalls disposition in bootgraph.pl

Browse source 
When bootgraph.pl parses a file, it gives one row
for each initcall's pid. But only few of them will
be displayed => the longest.

This patch corrects it by giving only a rows for pids
which have initcalls that will be displayed.
