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

Restore old (dis)allowedRequisites behaviour for self-references stdenv relies on this. So ignore self-references (but only in legacy non-structured attributes mode).

Harden tests' bash Use `set -u` and `set -o pipefail` to catch accidental mistakes and failures more strongly. - `set -u` catches the use of undefined variables - `set -o pipefail` catches failures (like `set -e`) earlier in the pipeline. This makes the tests a bit more robust. It is nice to read code not worrying about these spurious success paths (via uncaught) errors undermining the tests. Indeed, I caught some bugs doing this. There are a few tests where we run a command that should fail, and then search its output to make sure the failure message is one that we expect. Before, since the `grep` was the last command in the pipeline the exit code of those failing programs was silently ignored. Now with `set -o pipefail` it won't be, and we have to do something so the expected failure doesn't accidentally fail the test. To do that we use `expect` and a new `expectStderr` to check for the exact failing exit code. See the comments on each for why. `grep -q` is replaced with `grepQuiet`, see the comments on that function for why. `grep -v` when we just want the exit code is replaced with `grepInverse, see the comments on that function for why. `grep -q -v` together is, surprise surprise, replaced with `grepQuietInverse`, which is both combined.

Add disallowedReferences / disallowedRequisites For the "stdenv accidentally referring to bootstrap-tools", it seems easier to specify the path that we don't want to depend on, e.g. disallowedRequisites = [ bootstrapTools ];

`unsafeDiscardReferences` Adds a new boolean structured attribute `outputChecks.<output>.unsafeDiscardReferences` which disables scanning an output for runtime references. __structuredAttrs = true; outputChecks.out.unsafeDiscardReferences = true; This is useful when creating filesystem images containing their own embedded Nix store: they are self-contained blobs of data with no runtime dependencies. Setting this attribute requires the experimental feature `discard-references` to be enabled.
