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.

This tracer helps developers to optimize boot times: it records
the timings of the initcalls and traces key events and the identity
