Subject: [PATCH] tools/bootconfig: Add tracing_on support to helper scripts

Add ftrace.instance.INSTANCE.tracing_on support to ftrace2bconf.sh
and bconf2ftrace.sh.

commit 8490db06f914 ("tracing/boot: Add per-instance tracing_on
option support") added the per-instance tracing_on option,
but forgot to update the helper scripts.
