libpayload: Fix type issues

There were a number of type issues in libpayload that sneaked in
    with 903f8e0.

- size_t and ssize_t were conflicting with gcc builtins
    - some stdint types were used in libpayload but not defined
      in our stdint.h

With this patch it's possible to compile libpayload with the
    reference toolchain again.
