Subject: [PATCH -tip] Tracing/fastboot: Revert the stopping of the boot tracer

Since the patch that stopped the tracing after builtin-initcalls wasn't
a real solution of a bootgraph.pl's bug, we may continue to trace boot
after builtin initcalls. But we want to keep the stop_boot_trace function
for further uses.
