lib/libffi: Add libffi as a submodule.

This allows to build libffi from source together with micropython, and is useful for cross-compilation. Support for this was already merged previously, to use: make libffi make MICROPY_STANDALONE=1 (To both commands appropriate cross-compilition flags can be added).
