docker/jetson-nano/Dockerfile.python build failure

Hi @roflcoopter , thank you for the great work you're doing!

I'm trying to build a jetson-nano docker image on Jetson Nano. I'm getting this error message

 ---> Running in c15c74409958
gpg: directory '/root/.gnupg' created
gpg: keybox '/root/.gnupg/pubring.kbx' created
gpg: keyserver receive failed: No name
The command '/bin/sh -c gpg --batch --keyserver ha.pool.sks-keyservers.net --recv-keys "$GPG_KEY"' returned a non-zero code: 2

It seems, ha.pool.sks-keyservers.net is not supported anymore. Replacing it with the keyserver.ubuntu.com fixes the issue.

Thanks for the heads up! Will fix it in #306
