[scudo] Use stdint types for internal scudo types
`scudo::uptr` was defined as an `unsigned long` on 32-b platform,
while a `uintptr_t` is usually defined as an `unsigned int`.
This worked, this was not consistent, particularly with regard to
format string specifiers.
As suggested by Vitaly, since we are including `stdint.h`, define
the internal `scudo` integer types to those.
