cpio/initramfs: clarify their use in the help text
Recent mails on the list show that it is not very clear how to create an initial RAM fs with buildroot. So make this more explicit in the cpio and initramfs help texts. Hopefully this will reduce the /init debugging we have to do. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
