tools/bootconfig: Add --init option for bconf2ftrace.sh
Since the ftrace current setting may conflict with the new setting
from bootconfig, add the --init option to initialize ftrace before
setting for bconf2ftrace.sh.
E.g.
$ bconf2ftrace.sh --init boottrace.bconf
This initialization method copied from selftests/ftrace.
