In older versions of Gerrit the Change-Id field was inserted at the
start of the trailers. Commit 68296f71804feab2e0ae18ae33f834a8a41621e4
simplified the trailers code by using git trailers instead of custom
code but now inserts Change-Id at the end of the trailers section.
A consequence of this is that folks who sign-off their commits using
`git commit -s` now has the sign-off appear first followed by
Change-Id. If the user then runs `git commit -s --amend` to update
the change because the Sign-off-by line is not last, git inserts
a 2nd duplicate Signed-off-by line.
This patch simply restores the previous behaviour of the Gerrit
commit-msg hook where Change-Id would be inserted before the
Sign-off-by line to avoid this issue.

Most users of repo are also using Gerrit Code Review, and will want
the commit-msg hook to be automatically installed into their local
projects so that Change-Ids are assigned when commits are created,
not when they are first uploaded.
(cherry picked from commit a949fa5d20
but squashed with latest hook script from version 2.1.2)
