[#1689] Makefile: Create prepare-commit-msg hook too

`commit-msg` is ignored when `--no-verify` option is used, so there is
no way to ignore `pre-commit` while retaining `commit-msg` hook.
Ignoring pre-commit is useful, though, so we might add Change-Id in
`prepare-commit-msg` hook instead. It accepts more parameters, but the
first one is a file with the commit message, so we may reuse
`commit-msg` hook.
