4b1bd822ac Try to realise CA derivations during queryMissing
This enables nix to correctly report what will be fetched in the case
that everything is a cache hit.

Note however that if an intermediate build of something which is not
cached could still cause products to end up being substituted if the
intermediate build results in a CA path which is in the cache.

Fixes #8615.

c11836126b 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.

6352e20bc8 Remove --derivation from test
It doesn't do anything here, and in the next commit `show-derivation
will no longer accept this flag.

bf485dcf46 Properly normalize the content-addressed paths
Make sure that their timestamp are always normalized.
Otherwise, strange − and non-deterministic − things might happen, like

259d6778ef Move the CA tests to a sub-directory
Requires a slight update to the test infra to work properly, but
having the possibility to group tests that way makes the whole thing
quite cleaner imho
