fcc.sh isn't really a debug utility, it's more of a user contribution.
Also, there will be a FCoE EDD reading script that should be published
soon. It doesn't make sense to create a boot/ directory for this one
EDD script.
This patch creates a contrib/ directory and moves fcc.sh into it. This
contrib directory is also where the EDD script will live.
