slirp: Fix compiler warning for w64
Casting a pointer to an integer value must use uintptr_t or intptr_t (not long) for portable code. MinGW-w64 requires this because sizeof(long) != sizeof(void *) for w64 hosts, so casting to long raises a compiler warning. I use uintptr_t instead of intptr_t because changing the sign does not matter here and casting pointers to unsigned values seems more reasonable (the unsigned value is a non negative offset.
