Subject: [PATCH 1/3] nix: disable tests & examples

- the tests are not run or even built
- the examples are not installed
so it is better to simply disable them; this also avoids requiring
packages needed only for them.

Subject: [PATCH 2/3] Switch to system Catch2

In case the tests are enabled, require a system installed version of
Catch2:
- find it using its CMake config file
- use the Catch2::Catch2 CMake target
- stop using the tools/include subdirectory in the include path

Also adapt the Nix configuration for this.

Now that the system version of Catch2 is used, the embedded copy is no
more needed.
