Fix warnings like:

  In file included from uffd-unit-tests.c:8:
  uffd-unit-tests.c: In function ‘uffd_poison_handle_fault’:
  uffd-common.h:45:33: warning: format ‘%llu’ expects argument of type
  ‘long long unsigned int’, but argument 3 has type ‘__u64’ {aka ‘long
  unsigned int’} [-Wformat=]

By switching to unsigned long long for u64 for ppc64 builds.
