  Fix C compilation warning

gcc 8.3.0 emits this during python setup.py build:

persistent/cPersistence.c: In function ‘Per_repr’:
persistent/cPersistence.c:1481:44: warning: format ‘%llx’ expects argument of type ‘long long unsigned int’, but argument 4 has type ‘uint64_t’ {aka ‘long unsigned int’} [-Wformat=]
         snprintf(buf, sizeof(buf) - 1, "%llx", oid_value);
                                         ~~~^   ~~~~~~~~~
                                         %lx

<stdint.h> defines standard macros such as PRId64, PRIu64 and PRIx64 for
printing {u,}int64_t values, so let's use them.

  Oh, actually it was my mistake

PRIx64 is defined in <inttypes.h>, not <stdint.h>.

I hate C.
