I didn't try it, but I had a look at the code and the desired behavior may be achievable by setting
BZR_COMMIT_OPTIONS="--quiet"
in /etc/etckeeper/etckeeper.conf. See how it's used in /etc/etckeeper/commit.d/50vcs-commit. Could you please try it out and let us know if it works? I'm marking this bug report as Incomplete for now. Thanks!
