Ensure all functional scripts are (a) executable (b) have shebang This is good for shebang, and also good for future build system simplifications

Test nested sandboxing, and make nicer error We were bedeviled by sandboxing issues when working on the layered store. The problem ended up being that when we have nested nix builds, and the inner store is inside the build dir (e.g. store is `/build/nix-test/$name/store`, build dir is `/build`) bind mounts clobber each other and store paths cannot be found. After thoroughly cleaning up `local-derivation-goal.cc`, we might be able to make that work. But that is a lot of work. For now, we just fail earlier with a proper error message. Finally, test this: nested sandboxing without the problematic store dir should work, and with should fail with the expected error message.

Put functional tests in `tests/functional` I think it is bad for these reasons when `tests/` contains a mix of functional and integration tests - Concepts is harder to understand, the documentation makes a good unit vs functional vs integration distinction, but when the integration tests are just two subdirs within `tests/` this is not clear. - Source filtering in the `flake.nix` is more complex. We need to filter out some of the dirs from `tests/`, rather than simply pick the dirs we want and take all of them. This is a good sign the structure of what we are trying to do is not matching the structure of the files. With this change we have a clean: ```shell-session $ git show 'HEAD:tests' tree HEAD:tests functional/ installer/ nixos/ ```

No longer copy functional tests to the build dir This should make `_NIX_TEST_ACCEPT=1` work again, fixing #11369. Progress on #2503
