Title: build: fix `./configure` when nettle is not present

`PKG_CHECK_MODULES` will fail unless we give it an action to execute on
failure. When nettle is not available, we set `have_nettle` to `no`.

BTW, I appreciate that you keep autotools. While integrating an autotools project inside a CMake project is quite easy, the reverse is quite difficult.
