It depends on the zstd program being built, and passes it as an env variable. Just like datagen. But for datagen, we explicitly depend on it, while for zstd, we assume it's built as part of "all". This can be wrong in two cases: - when running individual tests, meson can (re)build just what is needed for that one test - a later patch will handle building zstd but not by default
We need to run it for the tests, even if programs are disabled. So if they are disabled, create a build rule for the program, but don't install it. Just make it available for the test itself.

Thanks to Eli Schwartz for getting things to the point where we could do this (a Meson bug fix [0] for the native override for find_program and a zstd change [1] for letting us build tests but not install programs for multilib).

This allows zstd to build with
-Dbin_programs=false -Dbin_tests=true, which is useful when you want to build a multilib library for libzstd, but not programs... and yet you also want to test that library.
