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.

tools/bootconfig: Add a script to generates bootconfig from ftrace
Add a ftrace2bconf.sh under tools/bootconfig/scripts which generates
a bootconfig file from the current ftrace settings.
To read the ftrace settings, ftrace2bconf.sh requires the root
privilege (or sudo). The ftrace2bconf.sh will output the bootconfig
to stdout and error messages to stderr, so usually you'll run it as
# ftrace2bconf.sh > ftrace.bconf
Note that some ftrace configurations are not supported. For example,
function-call/callgraph trace/notrace settings are not supported because
the wildcard has been expanded and lost in the ftrace anymore.
