LibC: Fix stdint.h macros on x86_64

Browse source 
x86_64 is an LP64 platform, so its `uint64_t` type is defined to be
`unsigned long`, not `unsigned long long` like on i686. This means that
the `UL` literal suffix should be used instead of `ULL`.

Furthermore, `uintptr_t` is 64 bits wide on x86_64, so defining
`UINTPTR_MAX` to be `UINT32_MAX` is also not correct.
