Make ssize_t an actual ssize_t
In the process of getting rid of compiler includes during in coreboot
and libpayload, we defined size_t and ssize_t ourselves, using a GCC
macro for size_t: __SIZE_TYPE__. Unfortunately, there is no
__SSIZE_TYPE__, so we temporarily redefine unsigned to signed to make
__SIZE_TYPE__ __SSIZE_TYPE__.
