tools: bootconfig: Add bootconfig command 

Add "bootconfig" command which operates the bootconfig
config-data on initrd image.

User can add/delete/verify the boot config on initrd
image using this command.

e.g.
Add a boot config to initrd image
 # bootconfig -a myboot.conf /boot/initrd.img

Remove it.
 # bootconfig -d /boot/initrd.img

Or verify (and show) it.
 # bootconfig /boot/initrd.img
