utils: Include stdint.h

Recent releases of glibc don't include the full stdint.h header in some
network headers included by utils.h.  So uintptr_t might not be defined.
Since we use fixed width integers, including the latter, all over the place
we make sure the complete file is included.

Fixes #2425.
