run-builder.sh fails to execute: docker: open .env no such file or directory.

This is for the disable-docker-proxy branch:

HypriotOS: root@black-pearl in ~/hypriot/rpi-docker-builder on disable-docker-proxy
$ ./run-builder.sh
+ pwd
+ pwd
+ docker run --rm=true --env-file=.env -v /root/hypriot/rpi-docker-builder/builder.sh:/builder.sh -v /root/hypriot/rpi-docker-builder/pkg-debian:/pkg-debian hypriot/rpi-docker-builder /builder.sh 1.5.0-dev -8-noproxy
docker: open .env: no such file or directory.
See 'docker run --help'.

Here's the steps to reproduce:

git clone https://github.com/hypriot/rpi-docker-builder.git
cd rpi-docker-builder
git checkout disable-docker-proxy
git pull origin disable-docker-proxy
./build.sh
./run-builder.sh

Looks like run-builder.sh is missing the two follow lines (they're in master) before docker run

mkdir -p dist
touch .env

I'll send a PR shortly once I've confirmed fix.

looks like the code at the end of the builder.sh was hardcoded to copy deb and tarball to s3. copying the code from the master version worked (which tests for the existence of AWS creds and dists directory).

Do you guys want a PR for this?
