[PATCH v2] scripts: check cc stable mailing list in commit

[Thomas Monjalon <thomas.monjalon@6wind.com>]

Add a check for commits fixing a released bug.
Such commits are found thanks to scripts/git-log-fixes.sh.
They must be sent CC: stable@dpdk.org.
In order to avoid forgetting CC, this mail header can be written
in the git commit message.
