python.pkgs.distro: Re-enable the package for now

Most tests are fine (only 20 out of 173 fail, 10 because lsb_release is
not available or returns exit code 3 and the other 10 might also fail
due to the sandboxed build environment).
Manual tests show that distro works as intended in a normal environment.
