git-codereview: make commit-msg hook play nicely with other systems

Gerrit requires 'Change-Id:' lines to be included in each commit
message, but they are not the only kind of 'metadata line' that might
appear in a commit message. Metadata lines observed by other systems
include 'Bug:' and 'Signed-off-by:'. This change ensures that the
commit-msg hook adds its 'Change-Id:' line to the set of metadata lines,
separated only by a single linefeed, rather than creating a new set by
inserting two line feeds.
