Felix Walter 62d563449f test: Remove the Unity wrappers for memory allocation functions
This adds a custom header that does explicitly not include the Unity
wrappers for malloc, free, etc. by defining the guard used by that header
file. This way we can remove the wrappers provided via the linker
altogether.
