Integrate aria2c support & fix unintended behavior for docker image (#1073)

* Update Dockerfile

* Create docker-bootstrap.sh

In addition to spawn cloudreve, this script generates password for aria2 so that users can take advantage of aria2 more conveniently instead of configuring aria2 by themselves.
