The thing we wanted to test was that building Nix without building or
running tests, and without depending on libraries only needed by tests,
works.
But since 6c8f4ef350, we can also install
unit tests, and during the conversion to using `package.nix` this
started happening more often (they go to a separate output though, so
this should be fine).
This adds more `... = false` to restore the original intent: don't run
unit test or functional tests, and don't install unit tests.
This was last upgraded in 788008385e, but
the version in Nixpkgs is a now a lot newer. I think the custom was
added to get ahead of Nixpkgs before, and so now that we are in fact
behind, it is no longer needed.
The Perl bindings are not part of Nix, but a downstream package, so they
don't belong in `package.nix`.
They don't really belong as an attribute on `nix` either, but we can
just leave that interface as is for now.
The problem was since switching to use libgit2, we had a package in our
closure (`http-parser`) that was always trying to build as a shared
object.

Today, with the tests inside a `tests` intermingled with the
corresponding library's source code, we have a few problems:
- We have to be careful that wildcards don't end up with tests being
built as part of Nix proper, or test headers being installed as part
of Nix proper.
- Tests in libraries but not executables is not right:
- It means each executable runs the previous unit tests again, because
it needs the libraries.
- It doesn't work right on Windows, which doesn't want you to load a
DLL just for the side global variable . It could be made to work
with the dlopen equivalent, but that's gross!
This reorg solves these problems.
There is a remaining problem which is that sibbling headers (like
`hash.hh` the test header vs `hash.hh` the main `libnixutil` header) end
up shadowing each other. This PR doesn't solve that. That is left as
future work for a future PR.

Closes#9343
See that issue for motivation.
Installing these is disabled by default, but we enable it (and the
additional output we want isntall these too so as not to clutter the
existing ones) to use in cross builds and dev shells.
This adds simple tests of the commit signature verification mechanism of
fetchGit and its flake input wrapper.
OpenSSH is added to the build dependencies since it's needed to create
a key when testing the functionality. It is neither a built- nor a
runtime dependency.
