package/docker-engine: add optional dependency on tini

Browse Source 
To provide an init process for containers if requested e.g. with
"docker run --init", Docker relies on tini to provide the init
binary. package/tini already provides the required
/usr/libexec/docker/docker-init symlink, the new option just selects
tini if enabled to prevent confusion over why docker-init is missing.

help
Support providing a minimal init process for containers,
using tini. Required to use "docker run --init".
This does not change the Docker engine build, the
docker-init symlink is provided by the tini package
itself. This option only adds the dependency.
