nixos/testing: Fix release.nix tests evaluation

Fixes the problem introduced by 12b3066aae46a8ccc3d21f54f668a3f4be344332
which caused nixos/release.nix to return the wrong attributes, while
intending to only affect nixos/lib's runTest.
This also removes callTest from the test options, because callTest is
only ever invoked by all-tests.nix.
