dtc and libfdt have been using Signed-off-by lines (as used in the Linux
kernel) for some time, like a lot of open source projects. However
Uwe Kleine-König pointed out we never really stated what they mean in our
context.
Add information on what the S-o-b line means in CONTRIBUTING.md - this is
essentially a quote of the same information from the kernel documentation,
with some tweaks to make sense in the new context.

README.md covers both general information for people using and building
the software, and more specific information for people contributing to
either dtc or libfdt. Split out the latter information into its own file
for easier reference.
