Automatically install Gerrit Code Review's commit-msg hook
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 a949fa5d202f0a1f812d7630f3e5bf0f02ca4e98
but squashed with latest hook script from version 2.1.2)
