nixos/borgbackup: add test

We had problems to get borg's own test suite running.
This test is intended to perform a quick smoke test to see whether we
have missed not any important dependency necessary to create backups
with borg.

tested with:

$ nix-build nixos/release.nix -A tests.borgbackup.x86_64-linux
