tracing/ftrace: make boot tracer select the sched_switch tracer
Impact: build fix
If the boot tracer is selected but not the sched_switch,
there will be a build failure:
kernel/built-in.o: In function `boot_trace_init':
trace_boot.c:(.text+0x5ee38): undefined reference to `sched_switch_trace'
kernel/built-in.o: In function `disable_boot_trace':
(.text+0x5eee1): undefined reference to `tracing_stop_cmdline_record'
kernel/built-in.o: In function `enable_boot_trace':
(.text+0x5ef11): undefined reference to `tracing_start_cmdline_record'
This patch fixes it.
