I've no objection to the actual config change, but the description is
little inaccurate IMHO. GitLab is not forcing a branch name change
into any existing repositories. It is entirely upto QEMU to decide
when to change our branch names. Forks of QEMU also won't get a new
branch name, because any branches in forks are inherited from what
exists in repository being forked and not arbitrarily renamed.

So, AFAICT, only brand new (ie empty) repositories will get 'main'
as the new default branch name.

IOW, I'd describe this as

  "We want to skip the checkpatch and DCO signoff jobs when
   pushing to the default branch. Currently this branch is
   called 'master', but we don't need to hardcode this in
   the CI configuration, because the $CI_DEFAULT_BRANCH
   env variable exposes it."
