Helper container for systems where build requirements (bash, curl, jq, make) are not available (for example on Synology)

Run the following command to enter the "build environment" (command may need to be run with `sudo` to work with the `docker` command):

```
$ ./run.sh
bash-4.4$

```

Afterwards you can execute the `setup.sh` script, modify `.env` to your liking and run any make commands:

```
bash-4.4# ./setup.sh
