[PATCH 1/2] tracing/boot: Fix config dependency for synthedic event

[Masami Hiramatsu]

Since commit 726721a51838 ("tracing: Move synthetic events to
a separate file") decoupled synthetic event from histogram,
boot-time tracing also has to check CONFIG_SYNTH_EVENT instead
of CONFIG_HIST_TRIGGERS.

Fixes: 726721a51838 ("tracing: Move synthetic events to a separate file")
