[PATCH 1/2] xstrtoll-tests: use %lld for long long

[Paul Eggert]

* tests/test-xstrtoll.c, tests/test-xstrtoull.c (__spec):
Do not assume long long is 64 bits, or that exact-width
64-bit types exist.  Although these assumptions are true
on current Gnulib platforms they are not true in general.
Also, GCC warns if PRId64 is "ld" but intmax_t is long long
even when long and long long are both 64 bits.
