build: skip kernel stack validation when building on macOS

Since we switched to 4.19, the kernel build checks for libelf to decide if
it should build tools for stack validation.

On macOS, this check fails during target/compile, but succeeds during package
build (because of the pkg-config path picking up target libraries).
