hook: add sign-off using "interpret-trailers"

Browse Source 
The sample hook to prepare the commit message before
a commit allows users to opt-in to add the sign-off
to the commit message. The sign-off is added at a place
that isn't consistent with the "-s" option of "git commit".
Further, it could go out of view in certain cases.

Add the sign-off in a way similar to "-s" option of
"git commit" using git's interpret-trailers command.

It works well in all cases except when the user invokes
"git commit" without any arguments. In that case manually
add a new line after the first line to ensure it's consistent
with the output of "-s" option.
