Description:

Docker ships with the ability to use journald logging. However, this package does not seem to compile with journald bindings. As a result, when changing the logdriver to `journald`, I am unable to read logs via the docker CLI. i.e. `docker logs my-container` will not work. The solution is to add `journald` to the `DOCKER_BUILDTAGS`

```
msg2 'Building daemon'
_fake_gopath_pushd docker-ce/components/engine github.com/docker/docker
DOCKER_GITCOMMIT=$(cd "$srcdir"/docker-ce && git rev-parse --short HEAD) \
DOCKER_BUILDTAGS='seccomp journald' \
VERSION=$pkgver-ce \
hack/make.sh dynbinary
_fake_gopath_popd
```
