discount: fix building with newer cmake.

Removed TESTS() as that was non-functional.

Tried running the tests manually, only to discover it tests/functions.sh
hardcodes `./echo`, `./cols`, and `./markdown`. And we don't seem to have
`cmd:cols` available on-tree.

Can be re-added when someone fixes it. For now, drop it to avoid
confusion.
